Cooper's my #1 choice in the first round, and I like him at center. Round two is a good spot for a safety. A lot depends on the combine, but Kenny Vaccaro would be a great selection there. In round three a guy like Alvin Baily is a great fit (OG, Arkansas). Kyle Long in the fourth is an athletic OT with big upside.
But it just depends who's there. If Zach Eifert is still on the board in the second he'd be tough to pass up. If Hankins or Williams is there in the mid-first, go DL and maybe Oday Aboushi/Baily then in 2/3. Swearinger in round four would be pretty good value at a position of high need, but Vaccaro and Reid are much better players, IMHO.
That's a pretty darn athletic future OL. I think Kowalski can play.
