you may still have ties. I am a little confused by the question. I am assuming you are talking H2H, if this is the case then, you are playing head to head per category, so each week in this proposed league would have a combined total of 11 wins/losses/ties.
It doesn't count 6 cats to 5 cats but each cat is individual game in itself.
in a points league, how do you make the categories so that batters and pitchers are even? is that a 5x5? what batting categories and what pitching categories should be used to balance pitching and batting
