I always thought it would be fun to have a 4 by 4 by 2 league.
I hate that saves and steals are 20 percent of your score in roto -- I think their place in roto is way more improtant than the way things work in the real world. Combine saves and steals into one category -- either contribute to your score (yea, I know that there are more steals to go around probably, this is just an off the cuff daydream) and have head to head be a roto category.
In other words, the team with the most head to head wins gets 10 points, so on so forth. Even if teams are way out of it, they still can be interested by the head to head element of it. And the winner wouldn't be subject to the vagaries of the post season.
