You might be right about him falling, but I find your criticism to be overly harsh...
First off, there are no questions regarding his work ethic... yeah, he gained 14 pounds when he weighed in at his Pro Day, but he'd hurt his hamstring, and couldn't work out... but in normal circumstances, he's known as a hard worker... here's what NFL Draft Scout has to say on the subject:
I've said it before, I see a little Michael Irvin in Nicks... I've seen him play in the ACC, mostly against the Virginia Cavs... but it's not just my eyeball assessment at work here, again I turn to to NFLDS for some analysis that reminded me of the Playmaker:
Hmmm, he's a big, physical receiver who excels on slants and working the sidelines... he plays with a "swagger"... yup, that sounds Irvin-esque to me...
So if he did fall to pick 51, I'd be happy to see the Boys claim him...
