I hate when people bring up "AA gutted the farm system" as though it has turned out terribly.
He gained huge surplus value in the deals he made. Graveman might be the best prospect of the bunch and he's a different guy now than when they traded him. Norris has been inconsistent/hurt since he was moved, Boyd might be a number 5, Hoffman has been bad. Barreto is a nice prospect but he's still outside the top 50 prospects on some lists. Nick Wells/Jake Brentz are nobodies.
Without those trades the team doesn't make the playoffs the last 2 years. Hell you could probably trade Donaldson and Tulo for more right now than what they gave up at the time 2 years ago
