DE Josh Sweat, Chesapeake (Va.) Oscar Smith
Why Walker has an edge:
Walker is one of Arizona's top 2015 prospects, and that has as much to do with his technique as it does with his ideal, 6-foot-5 frame. He's a polished tackle for his age, and he carries almost no bad weight. He has the body of an elite-level offensive lineman, and his long arms make him a nightmare in camp settings. But what gives Walker the real advantage is that he has plenty of experience on the camp circuit. Most recently, he handled some highly regarded 2014 prospects at the Phoenix stop of the Rivals Camp Series presented by Under Armour. He has added a little weight since then, and as time goes on and he keeps adding muscle, Walker is developing into a certifiable force.

Why Sweat has an edge:
Sweat is a freakishly athletic defensive end who can do a number of things well. At 6-foot-4, 223 pounds with great explosiveness off the line, Sweat is deadly when rushing to the outside. He is strong enough to withstand an offensive lineman's initial punch, and he is experienced enough to know how to brush the offensive lineman's hands off of him. At his last camp, it looked like Sweat had a lot of room left in his frame to fill out. It will be interesting to see how he has developed his body. Sweat needed to improve his pass-rushing moves to the inside, and this matchup will certainly test him in that area.
-- Adam Friedman, Mid-Atlantic recruiting analyst
Overall edge:
While Sweat is an athletic and well-coached rush end, I think Walker has the edge because he does well with his length and quick feet to the outside, which is where Sweat makes his living. A counter move might mix things up, but Sweat has shown a trend of working outside and the wingspan of Walker will allow him to ride him outside in this matchup. -- Mike Farrell, national recruiting analyst
