Supposedly there is an effect from the number of NBA draft picks a coach has produced, but I have no idea how big an effect that is (and it would only have a heavy impact in D1 battles). Also, if a coach has a bad reputation then recruits won't believe his promises, but again, I don't know if this has a significant impact. I think that the three things you mention (money, distance, and prestige) will usually swamp any variables relating to the coach himself.
