Rumor is a concussion issue.
That's not really coming up in any of the actual reports, either, though. Not saying neither problem exists. There are players who drop every year and you wonder why before learning that there was a medical concern. We'll see how it plays out.
I do find it interesting that several reports mention him shooting up the boards when he stood out in Senior Bowl practices, but that teams may not be as high on him as that because of limited hip flexibility and the fact that he didn't do all the drills at the combine (despite standing out in the ones that he did). In some ways, what is being said about him reminds me of Frederick.
Depending on how the board plays out, I'd like him to be the pick, but if it is Barton instead or we trade down and get Frazier, I don't have a problem with that. Not going to be as pleased if we wait to address one of our top needs IMO until the third round or later.
