## Comparing CoinRoster Prices to Market Odds

This post is about trying to beat the odds on CoinRoster daily fantasy golf, a game where the fantasy points are determined based on score to par. The worst score to par becomes zero and each fantasy point is awarded based on the difference from the worst score. For example, if the last placed player has a real world score to par of +4 and the first placed player has a score to par of -10, then the first placed player will have 14 fantasy points. All other players are assigned a relative point value.  Six players are drafted to each roster, so the total score of each roster is the sum of the individual scores of all players on each roster.

My goal is to find some drafting strategies that take advantage of the difference between the price of golfers available to draft on CoinRoster versus the odds of betting on golfers to win the tournament.

The price of each player in the CoinRoster draft is relative to their world golf ranking. But I wondered how to determine whether this is a good price or a bad one? And which factors should I consider while attempting to make this determination?

I have compared the prices of the players available to draft with their odds of winning the tournament. I know from previous research that the odds of each player is related to their expected relative score to par.

I made a list of all players available to draft using excel with their associated price on CoinRoster, then I calculated the percentage chance implied by the prices of each players in the draft by taking their drafting price divided by the sum of all player prices. So if a player costs \$3000 to draft and the sum of all players prices is \$80,000, then this implies 3.75% (\$3,000 / \$80,000).

By finding this drafting price ratio, it gives me an “implied” percentage chance of each player having the most fantasy points based on CoinRoster’s drafting price. Then for curiosity’s sake, I converted those implied percentage numbers into decimal odds. The next thing I did was add a column of each player’s odds of winning the tournament and then I converted that into a percentage number also. Now I can compare apples to apples using their percentage chances.

With this information, I can eyeball and compare the odds numbers and the percentage numbers (which are the same value, but just displayed in different formats). I can also rank and sort the data in various ways using excel, so I subtracted the implied market percentage chance from the implied price percentage chance to uncover the difference between the two numbers.

By subtracting the two prices (the percentage chance implied by drafting price with the percentage chance implied in the player’s betting odds) I can notice if the price for a player available to draft is relatively lower on CoinRoster than is implied by their market odds. If the player is cheap and represents good value to draft their price on CoinRoster will be lower than implied by their betting odds. This means the player is cheap to draft, but if a player’s market odds are lower than their relative drafting price on CoinRoster, the player is expensive.

The table below shows the numbers for the BMW Championship. The table is ranked best to worst value.  Dustin Johnson has the best value for this tournament according to this formula. His odds were 9.36 (which implies a more than 10% chance he will win the tournament, and thereby have the best score to par) but his CoinRoster price was relatively cheap (even though he is the second highest priced player). Justin Rose, Rory McIlroy, and Hideki Matsuyama are also some of the most relatively best priced players.

Tiger Woods also has the third highest relative value to draft. This makes sense since Tiger’s world golf ranking (which the CoinRoster drafting price is based on) is relatively low compared to his chances of winning the tournament. So intuitively, this affirms my belief that I’m on the right track.

Some of the most expensive players on CoinRoster are Tyrrell Hatton, Alex Noren, Brian Harman, Kevin Kisner, and Peter Uihlein.

## Opening a FanDuel Account

Today I’m going to open a FanDuel account. My plan is to make a deposit and play PGA and NHL fantasy.

The first step to to enter your e-mail address, username, and password. Once I enter these credentials, FanDuel takes me to a page where I’m asked to choose my favorite sport. In my case, this is golf (and it seems like FanDuel assumes I only have 1 favorite sport).

The first thing I’m noticing right away is its been a few minutes after opening my account and FanDuel seems intent on prompting me to enter a free contest (which I’m not interested in, I’d rather just play PGA for stakes). So I quickly choose a seemingly random lineup of players and enter the free signup contest.

After hastily entering a free contest, I’m now ready to make a deposit. I choose the \$100 amount and enter my credit card credentials. FanDuel users can also deposit using PayPal. But after trying a few different times, I was unable to make a deposit using either of these methods. I assume my credit card (visa) that could not be processed (as I tried paying with visa by way of my PayPal account also), I guess my card issuer might not process payment for FanDuel, I’m just guessing. But after I disabled the popup blocker from my browser and tried making a PayPal deposit debiting my bank account directly instead of my credit card, I was able to make a \$100 deposit and receive a \$20 deposit bonus.

## Free Play at CoinRoster Fantasy Sports

My friends are promoting their fantasy sports site, based on bitcoin, called CoinRoster.

As a special promotion, they are giving away 0.02 bitcoins worth of free play to any new user that signs up using a link from my page!

The bitcoins can be used to play on CoinRoster, but they can’t be withdrawn until they have been played 20 times, which in this case is 0.40 bitcoins worth of play.

For those of you who are unfamiliar with bitcoins, at the time of writing these 0.02 bitcoins are worth about \$40 Canadian dollars or \$25 US dollars.

I’d say the best games they currently offer are about Golf. They have a weekly golf fantasy game and also have a daily hockey game. In the summer they tell me they’ll have a baseball game going and in the fall they will do NFL.

## Does the UL IC help Ko & Henderson?

This week the LPGA Tour hosts the UL International Crown, where 8 teams of 4 players compete based on nationality in a match play format. Several players have commented on how this event, plus the Olympics has made their schedules busier than normal. Christie Kerr said she is playing 5 weeks in a row because of this event and this is the most in a row she has played since her early 20s. Professional golfers have a demanding travel schedule, so getting rest and off weeks is important to rejuvenate their minds and body as professional golf requires intense focus.

Certain countries have a deeper pool of professional golfers than others. Some countries such as the US have a deep pool of high ranked players, but others only have a few top players and not much else.  Take New Zealand & Canada as examples. The top two ranked players in the world right now are Lydia Ko who is Kiwi and Brooke Henderson who is Canadian. But they are from countries without deep pools of top ranked golfers, so because of the qualifying format, their countries did not qualify for the UL International Crown.  This gives them a critical week off going into the British Open the following week.

For Brooke Henderson, a week off was a necessity. If Henderson had to play the UL International Crown, it would have meant a non-stop string of big tournaments in a row since she is the 2 time defending champion in Portland which is followed by the US Open, then the British Open, Olympics, and then two Canadian events in a row including the Canadian Open and the Manulife, and then the last major of the year at the Evian.

At the same time, I think the schedule also hurts the top ranked American and Korean players such as Lexi Thompson, Stacy Lewis, Soyeon Ryu, Ingee Chun, and Seiyoung Kim. It also helps players that don’t have to play in either/or the UL IC or Olympics such as Ha-Na Jang, Anna Nordqvist and Suzanne Pettersen, Jessica Korda, and Sung Hyun Park.  Adjust your odds, and look for the players who have got some breaks to play well at the last few majors of the year.

## Tiger Woods Retirement?

Its impossible to determine who is the greatest golfer of all time. Golf has been played for over 100 years and the equipment and course design is always evolving. We can however, confidently narrow down the greatest players to a shortlist, which would obviously include names such as Jack Nicklaus, Bobby Jones, and Young Tom Morris. Tiger Woods should also be considered one of the greatest golfers of all time. He revolutionized the game by making it more powerful and precise, thereby forcing players to become more athletic. The aspects to the game that Tiger pioneered are as important as Young Tom Morris introduced wedges, shot shaping, and backspin. Tiger also set a new standard for golf as a global game played for huge purses.  Tiger will continue to be one of the highest earning athletes until his death.

Jack Nicklaus won the Masters at age 46.  Winning a major at this age is less likely today because of the style of play that Tiger Woods made commonplace in professional golf.  It is now more likely that professional golfers have a competitive career similar to a basketball or baseball players because of the pressure their bodies take in order to push themselves to compete at a high level.

#### Tiger Woods’ Private Struggles

Turning 40, the golfer talks about his high and lows on and off the course By Lorne Rubenstein Tiger Woods was raised to be a champion. Groomed by a father who put a golf club in his hands before he could walk, Woods has been one of the most dominant athletes of all time since turning pro at 20 in the summer of 1996.

## Rory McIlroy Open Odds

I was disappointed to learn that Rory McIlroy has injured his ankle recently, and its unlikely he will play in the Open Championship. After hearing the news, I immediately checked Betfair to see his odds. To my delight, Betfair posted a market on whether Rory will play at all. At this moment, the market is 1.20 to 1.30 that he will NOT play in the Open. Now even if he DOES play, how effective will he be?  This guy swings at 120 miles per hour, and puts a lot of torque and strain on his joints. To my surprise, the market on whether Rory will win the Open is currently 14.5 to 15.0.

Rory McIlroy will give the media an update later in the week, but at this point it is probable Rory will not win the open and 15 to 1 odds would be an incredible steal.

## Frank Nobilo weird grunts during Masters broadcast

It was by far the funniest part of the Masters broadcast this year, during the 3:13 minute mark of the CBS coverage, during the 11th hole fly-over, Frank Nobilo’s commentary is broken up by some really weird grunts.  Its almost like he was squeezing out some gas.  Sir Nick Faldo turns the commentary over to Nobilo who starts describing the 11th hole while a flyover shows on the screen, but then twice during his description interrupts with some soft grunts.  Very likely he was tooting on air during the Masters.  Other possible explanations include getting pleasured under the table during the commentary.

## Tiger Woods Over?

I’m a Tiger Woods fan.  He was an incredible golfer and took professional golf in a new more athletic direction. But now its clear the style of golf that Tiger plays, might not allow him to continue competing on the PGA Tour into his 40s.  He swings hard and puts a lot of strain on his body.  This intensity will probably prevent him from beating Nicklaus’ major records.
