I know this thread is about Pryor v. Clinton-Dix, but Ward and Brooks have been mentioned, so I want to add this... I just watched a few of the draftbreakdown.com cutups on Ward. My thoughts:
Really easy mover. Fluid. Versatile. Can be moved all over the secondary, even playing in the slot at a high level. Plays the ball in the air well (times his break and rakes at the ball at the right moment).
My problem with him is that he's not a reliable tackler. He's very small (5'10 3/8", 191 lbs.) and plays that way when the ball is on the ground. His coverage ability and range are there for him to be a true FS, but his tackling will dissuade coaches from putting him in that position. His size is that of a smaller CB as a matter of fact, so although I appreciate him for what it is, I'm not sure he's a layup as a full-time FS.
Terrence Brooks is also smallish (5'11, 197 with very short arms and small hands). That's not good, but he plays bigger than that. You can see that he's more aggressive in his downhill breaks, and wraps up and drives through the ball carrier as opposed to cutting the guy down Deion-style (like Ward).
Both these guys are good players and could help us. I think I'd be a bit more comfortable putting Brooks in that full-time FS role, but Ward provides that extra layer of being a better man/slot cover guy. Since Scandrick is so good in the slot, and Carr/Claiborne aren't going anywhere in the next couple years, that reduces Ward's value just a bit (since it would likely take an injury for us to use him a ton in the slot).
Overall... these top 4 S's would all help us, as they'd all upgrade our overall quality in the secondary. But I wouldn't be overly thrilled with Ha Ha/Pryor in the 1st, or Ward/Brooks in the 2nd. Totally thrilled to score any of these guys a round later.
