Again...
JP was a dick, called out players in the media, some of which weren't even Blue Jays (Adam Dunn, who wouldn't sign with the Jays so JP blasted him), originally hired Gibbons, signed Wells to a ridiculous contract, and while I like the moneyball philosophy, I think most people were happy when he got canned because he had worn out his welcome here big time. Plus, if he was so great, why isn't he another team's GM yet?
Bottom line, they both suck, but at least AA has a good reputation around the league. You're basically asking us to pick the tallest midget though.
