Mike Adams: Adams was big enough to impress in person. He's very tall and heavy without looking loose. While a bit of a waist-bender and a tad stiff, Adams has elite potential as a pass protector. As a run blocker, Adams was rusty and raw. He'll need work to improve leverage and drive off the ball.
Tony Bergstrom: A guard at the next level, Bergstrom didn't disappoint. A bit rusty when practices began early in the week, Bergstrom looked solid in one-on-one drills and was holding his own in pass protection. He needs technique development, but there's more potential here than previously seen.
Mike Brewster: Brewster had some issues with the center-snap exchange, notably with quarterback Russell Wilson. Impressive in one-on-one interviews, Brewster was intelligent and humorous. Watching him snap and shuffle, Brewster is quick enough to handle speed rushers. He doesn't look strong enough to handle nose tackles though.
Rishaw Johnson: A small-school guy from California (PA), Johnson was quickly overmatched. Playing mostly at center after replacing Garth Gerhart, Johnson took longer than expected to get used to a new quarterback. His snaps were both high in shotgun and coming up short when under center.
Senio Kelemete: Playing both guard and tackle, Kelemete was impressive showing off the knee bend that scouts love so much. His versatility will be key to his draft stock, proving he can handle two positions equally well. His hand placement drew multiple plus signs in my notes.
Kelechi Osemele: The most powerful blocker on the North roster, Osemele was dominant at the point of attack. The best defensive linemen were being stonewalled when entering his zone. Osemele looks natural at guard and is quick enough to pull and trap. He looked good moving laterally.
Mitchell Schwartz: Long arms were the story here. Schwartz measured 33 1/8" long, very good for a tackle. He's a right tackle and showed good strength. Schwartz isn't much of a run blocker, but there is potential as a drive blocker. Currently he looks better walling off defenders.
Johnnie Troutman: Noted mostly for his interview with the somewhat local Kansas City Chiefs, Troutman didn't jump off the field at me. His play at guard was overshadowed by Kelemete, Osemele and Zeitler. Troutman's technique needs a ton of work.
Kevin Zeitler: Despite horrible attempts to play center, Zeitler is a guard. He's a mauler who has classic phone-booth technique: great inside, poor when asked to move. Zeitler looks like a right guard in a power scheme where his strength can dominate at the point of attack.
Cordy Glenn: Glenn may see a move to guard, and he did work at both this week. The first impression on Green is his massive size. He carries his weight well, but not as clean as others. Glenn did look stiff at times and slow to react, but loosened up as practices wore on. He's a natural athlete whom I like best inside.
Jeff Allen: A surprising player, especially in one-on-one pass rushing drills. Allen is able to engage the defender and use leverage to create a stalwart. He was strong at the point of attack with good hand placement. Allen's probably a right tackle, but I like him there after what we saw this week.
Matt McCants: A local kid from UAB, McCants is a massive prospect at 6'7" and 310 lbs. He looks the part, but is otherwise very raw at tackle. He tried winning on athleticism but was quickly tossed around by Melvin Ingram and Courtney Upshaw. McCants looks like a major project.
Zebrie Sanders: Sanders' athletic ability and experience at left and right tackle helped out a lot this week. He is very natural and fluid, with a good kick-slide. I was impressed with Sanders getting to the corner, where he was able to use his length to cut off rushers. You'd like to see him lunge less, but the potential is there.
Will Blackwell: Blackwell has flashed at guard, quickly catching my attention early on. He's more stout than I expected from film study and used his size well to seal defenders. Blackwell held his own in individual drills and was looking good as a combo blocker.
Ben Jones: The best center seen this week, Jones' ball placement was superior when compared to the other snappers here. He is very quick off the ball and uses his size well to wall off defenders. Driving guys off the ball isn't what Jones does best, but he's a good combo blocker and agile enough to run stretch plays.
James Brown: Brown flashed in one-on-one drills, surprising by holding his own and showing good footwork and slide ability. He's from Troy, so you worry about level of competition on film. This week was a good chance to see good athletic ability and developmental potential in Brown.
William Vlachos: Vlachos timing was good, but he didn't show up in individual drills. You always wonder if a player like this comes from a system instead of being a dominant player, and that's the line on Vlachos right now. He has average technique and lacks athletic ability.
Philip Blake: The Baylor center struggled at times with under-center snaps, something he did little of in college. Blake settled down by midweek and was getting his snaps on time and deep enough for the quarterback. His first step was quick, as was his punch. Blake's worth taking a new look at.
