I do agree judging a trade after you find out how the prospects developed isn't the right way to judge it. However, most of those players in that specific deal were at their max value at that time, AA traded them at the right time. He also traded them right near the deadline when the Jays need was pitching. You could look at other potential deals but he made the right move to acquire Happ if that was the best pitcher they could have gotten for those prospects at the time (along with Lyon/Carpenter). Recognizing that they weren't going to impact the Jays, likely ever except the off chance with Wojo.
