In standard 4×4 and 5×5 leagues, OBP is clearly so much superior a rate stat to BA and we all know it, that I’m shocked everyone hasn’t made the change. Once you’re tried it you’ll never go back, because players values actually reflect their values (minus defense) in the major leagues.
But it’s hard to get people to change, which is why only one of my leagues use OBP instead of BA. We’ve talked about making the change in Tout Wars, but since part of the league’s goal is to offer draft guidance, it isn’t going to happen until you all switch over. Get going!
