Hard to say. AA build a top 5 farm team, and when it was time for him to transition into a play off contender he fell apart and now we have no farm and are still out of the playoffs.
JP he was more of an all or nothing kind of guy which he put together some "solid" seasons but still no playoffs and never a thought at all about the farm system much it seemed.
Not going to vote on this one just pointing observations lol.
