ESPN looks great! But a max innings pitched is just... ungood. Yahoo has it right with a minimum innings pitched. If you have no minimum innings pitched, you leave yourself open to a HUGE loophole! If I were to play in your league, I would draft the best middle reliever in the game. Pitch him one inning per week. That would win me half the pitching categories. And then for the rest of my draft I wouldn't have to draft any more pitchers!
I would consider moving to Yahoo so that you can have a minimum innings pitched. Until ESPN fixes that loophole, I'll never play there.
