In daily fantasy hockey, stacking is a key strategy in tournaments. We want to correlate our lineups with up to four players to maximize our upside -- if one player on a line is scoring goals, it's likely that his linemates are getting assists, as well.
Ideally, we want players who will get a lot of ice time together on an even-strength line and a power-play line. Two good resources for line combinations are LeftWingLock.com and DailyFaceoff.com, so be sure to check those sites for updated line information.
Football season may have ended yesterday, but the NHL season still has months left.
