Any idiot with a top 15 pick in that 2011 draft was gonna get a good player, so Hamilton doesn't really seem that impressive.
Jim Benning, Matt's uncle, was the assistant GM for the 2012 draft, and it was likely his call to take his nephew in the 6th round that year. Most 6th round picks don't sniff the big league, so might as well have fun and draft some family.
Pasta, Donato, Heinen were technically drafted by Chiarelli, but at that point Assistant GM Don Sweeney, and scouting director Keith Gretzky were calling the shots at the draft.
Of your proposed good Chiarelli draft picks, that leaves Spooner, who's a fine player. I'll give him that.
I don't how he's done since he left, but with the Bruins, Chiarelli's drafting was objectively really bad.
