I'm not sure what exactly you are looking for. Winning a weaker (than normal) division doesn't mean AA's doing a good job. However, the Jays based on run differential and other factors should be much better than their record indicates. When they employ a manager that doesn't know who his best relievers are, values offense over defense leading to stupidity like Colabello in the outfield, is dumb enough to think Navarro is a good enough hitter to justify the lost runs on defense by putting Edwin at first, etc, etc, etc, etc, etc, it's not a surprise that their record in one run games is so bad and they are playing well below their run differential.
AA and Gibbons both stink. A better GM would have rounded out the roster better, and a better manager puts this team in a better position to win the close games. They both need to go.
