OK. Baseball rules. I think the bias is in that robo calculates the probabilities better, but I can't prove that either. I am also struggling with this idea of home park adjustments, so that's where my head is. I just drafted (LL1) both Cirillo and David Bell. Cirillo's stats are clearly better, but the PB value says Bell is better when he plays. When I play against robo, does he know something that I don't?
