Stacking a daily fantasy lineup means concentrating your draft picks on players who will score together. For fantasy hockey, this means drafting players on the same line. For NFL this means pairing QBs with their receivers. For fantasy golf, stacking could mean drafting players set to tee off in the same flight (and therefore the same weather/conditions). If the golf course is playing tougher or easier at a particular time of day, there can be an advantage to stacking. Think about extreme cases like the Open where the weather conditions have a big impact, or a golf tournament with rain delays, you can stack by drafting golfers who are likely to tee off at the same time.
