Don't jump the gun here - I'm not saying they shouldn't have drafted him. He's a great fit in Portland and my personal pick for ROY. I simply wonder if Portland made a mistake taking him at 6 instead of 11 and missing out on another top prospect.
Both Barnes and Drummond were still on the board when Portland picked. There were solid indications that teams 7-10 were leaning along the lines of:
Golden State: best available meaning either Barnes or Drummond
Toronto: Terence Ross (a SG with a jumper)
Detroit: a center to pair with Monroe
New Orleans: Austin Rivers
The risk was minimal, so is the difference between Meyers Leonard and Drummond/Barnes worth it?
