Here's some info on him from this link: http://www.cbssports.com/nfl/draft/players/1272234
Strengths: Good athlete, powerful, fast, quick off the snap, relentless, can hurdle blockers to make tackles. Has strong hands and can punch with power. Wrestling background clearly helps hand fighting skills. Can shed and pursue with surprising speed. Makes plays behind the LOS and in pursuit. Steady improvement, best effort was final game.
Weaknesses: Is slightly top heavy due to huge upper body. May have trouble anchoring at the next level. Does not turn or move well laterally. If initial move/punch fails, usually gets high and can't beat the block. Doesn't have a lot of pass rush moves. NFL Comparison: Tyson Jackson - Kansas City Chiefs --Brad Noel
04/30/2012 - Seattle general manager John Schneider said the team decided to draft North Carolina defensive tackle J.R. Sweezy and move him to offensive guard instead of drafting an offensive lineman in the seventh round because his athleticism is better than any offensive line prospect available at that spot. Seattle offensive line coach Tom Cable went down to North Carolina to work Sweezy out, and came away impressed. "You get to a point in the draft where there's a certain level of athleticism," Schneider said. "There's a little bit of a cut off all the way through it. And here's a guy that's a real tough, aggressive, quick defensive lineman who the staff at N.C. State would tell you out the door, 'Hey, this guy has a chance to be a really good offensive lineman, too." - The Sports Xchange
