Yeah, league rules and scoring rules dominate the answers. I play in H2H leagues, but instead of 5x5 or 6x5 or whatever, it is fantasy points. (hosted by Sandbox, for better or worse).
Those leagues require solid SP bigtime. I played in one league where the guy tried the "fish the WW for SP" and got clobbered. Especially if there is a fixed number of games (162) for position players and starters.
H2H is a different animal if it's fantasy points, though. I prefer it to 5x5, so maybe I'm not such a traditionalist. But the trash talking is far better!
