Quick is a bust, plain and simple, based on where he was drafted and his production, and the guys taken after him and their production. To me, that is how you rate a player a bust or not. As of now, he is a bust. Could he turn it around, yes, but is it likely to happen, no. You can't blame QB play on his lack of production, because look at Alshon Jeffery and another guy taken after Quick albeit the supplimental draft, Josh Gordon. Both have QBs comparable to Clemens, and both are producing rediculous stats (without Cutler Jeffery was actually producing more).
Hard to disagree when looking at the numbers. I'd even leave Gordon and Jeffery out of the conversation because they are so freakish and so good at this point, it makes it seem like an unfair comparison. Let's look at a couple of other names though:
Quick - 29/458 4TD
Stephen Hill - 45/594 4TD
Ryan Broyles - 30/395 2TD
Rueben Randle - 60/909 9TD
T.J. Graham - 51/621 2TD
Mohamed Sanu - 62/597 6TD
T.Y. Hilton - 121/1,789 12TD
Chris Givens - 76/1,267 3TD
Travis Benjamin - 23/403 2TD
Jarius Wright - 46/713 5TD
Keshawn Martin - 31/336 3TD
Marvin Jones - 64/852 10TD
LaVon Brazil - 22/336 2TD
Rishard Matthews - 48/541 2TD
Now, this isn't EVERY WR taken after Quick but it's most of them in that 2012 draft.
Quick has some major work to do to even be a regularly productive receiver. Hard not to say he's a bust so far.
