I am almost positive that you have coaches turned on as when you don't, coaches aren't listed when you click "coaches" on the league reports site. I don't even have a AAA coach as his contract ran out last season. It lists how much money they make and when they're signed for. I'm not sure how much effect that has, but if it's turned on, which it appears it is, I think not having a coach at all would hurt prospects. I also don't have a hitting coach either...
