Saints Mock Drafts

I've never seen him live or on tape till your post. Thx much. On highlight tape, he looks like the #1 pick. He's big, athletic and moves well around the pocket. He has all throws: perfect back shoulder, precision sideline throws, slants where he leads the receivers open, makes quick 2nd reads and a cannon of an arm where he hits 50 yarders in perfect stride.

So what's the knocks on this guy?
I'm No Scout... but the first thing that I see is that this guy locks on one receiver and waits to throw to him at the right time or throw him open. In other words no progressions. This will get you killed in the NFL. Watch that film again and you'll see my point. I could be wrong but it may be something he can be coached out of... but what do I know?
