Mike Iupati, Idaho
If there was any doubt about the small-school Iupati's ability to handle big-time competition, those fears have disappeared. At 6-foot-5 and 325 pounds and as strong as an ox, forget about bull rushing him. And with feet good enough that some scouts wonder if he could play left tackle, nobody is going to beat him with inside speed. With the longest arms of any prospect and nimble feet for his size, he's hands down the best lineman in Mobile.
Ciron Black, LSU
If Iupati is the best lineman, than Black is the best left tackle prospect. That might not be saying much given the way the other left tackles have performed this week. Still, no position is more important to the offensive line, so Black gets extra credit for playing well. The 331-pounder had no trouble handling speed rusher Brandon Lang. That was impressive.
John Jerry, Mississippi
Is he a guard or a right tackle? Jerry thinks guard might be his best spot, because that's where he gets to put his mean streak to use. But teams need tackles to protect the quarterback, and Jerry has looked good in pass protection. At 6-foot-5 and 332 pounds with 34 1/4-inch arms, he'll probably get a long look at right tackle by whoever drafts him.
Matt Tennant, Boston College
Tennant is probably the best center here. At 6-foot-4 and 290 pounds, Tennant is the "runt" of the offensive linemen, but he had no trouble handling North Carolina's 331-pound Cam Thomas. He went 1-1 against Cal's 291-pound fire hydrant, Tyson Alualu.
The 6-foot-2, 300-pound Walton is challenging Tennant for top honors among the senior centers. At 6-2, 300, Walton has more bulk and plays with equally good fundamentals. He's also got some nasty to them, like when he shoved Lamarr Houston to the turf at the end of a snap.
We'll call this grading on a curve. Ducasse (6-4 1/2, 326), a stud left tackle at Massachusetts, doesn't appear to have the feet to play tackle in the NFL. That's why scouts think he'll make a better guard. So, while Ducasse has been thrashed repeatedly in one-on-ones at practice, it probably doesn't bode poorly for his draft stock.
In two matchups against Georgia's talented Jeff Owens during one-on-one pass blocking, Byers (6-3, 299) won impressively, including putting Owens to the turf.
Selvish Capers, West Virginia
If Capers (6-4 1/2, 304) can stay low, he's got a chance to be a really good left tackle. Instead, though, outside pass rushers have attacked Capers' outside shoulder and ducked underneath him to get to the quarterback.
