I don't think the talent level is real low in QB's, there are a couple that have very high ceilings, but all of them have chinks in their games that also mark them as high bust potential. Some of them due to lack of physical talent, some due to body build, and some due to poor mechanics. The latter group is the one worth taking the risk on, but only in the 2nd or 3rd round IMHO. You can coach up bad mechanics if the QB adapts to the coaching, but thats always so hit and miss.
Hurst really scares me, and personally, I hope he doesn't play another down of football in his life (for his sake). Then again, I don't really know the situation (nobody does), and if he's there and the Jets think hes mentally ok, that has great reward potential. Would be a steal if he works out.
Bernard will be gone by #34. Some team will take him at the end of the first. Hopkins will probably be gone by #39 as well. He will shoot up draft boards after the combine.
Care to explain why? Several mocks I have seen have both these men going in the early 2nd. Hopkins can rise but as of right now he's the 4-5th best WR, and although Bernard is the best RB in this draft teams tend not to reach on RBs due to their short careers.
