1. Damian Prince, Bishop McNamara High, Forestville, Md.
Skinny: It speaks volumes about sophomore defensive end Josh Sweat's ability that he faced off with the top offensive lineman in attendance, and went 4-0 in their one-on-ones. While Sweat got the better of Prince, that didn't take away from the flashes of ability Prince displayed. He is light on his feet for his size and sinks well into his base, absorbing rushers. Sweat got the better of Prince in this setting, but I saw enough to know that even up the odds by putting the pads on and including a running game, and Prince can be dominating.
2. Patrick Allen, Franklin High, Reisterstown, Md.
Skinny: Allen, a class of 2015 prospect, lined up at left guard next to Prince at times, and he was the only player to win a rep against five-Star defensive tackle Andrew Brown. Allen used his hands as well as any of the offensive linemen to steer them in the direction he wanted as they tried to spin and rip their way out of his grasp.
3. Nick Clarke, Atlee High, Mechanicsville, Va.
Skinny: The offensive line looked a little timid after watching Sweat and Brown through their first four reps on defense, but Clarke lined up at center and reestablished some order and toughness. At one point, Clarke even took a wicked head slap and still won his rep. He has good size, strength, and I have no doubt about his ability to do the dirty work in the middle of the line.
4. Alec Eberle, Atlee High, Mechanicsville, Va.
Skinny: Eberle had a very similar day to Clarke. He lined up at center and guard during various reps, and though a but undersized, he still showed no fear in stepping in front of the power rushers, and using leverage like a wrestler sometimes does to win his reps. He was smaller than most of the defensive linemen he blocked, but he showed good flexibility, strength, leverage, and balance.
5. Quarvez Boulware, Friendship Collegiate High, Washington, D.C.
Skinny: Another super sophomore in the group of big men, Boulware lined up at right tackle and showed feet as quick as anyone not named Prince. He had an advanced drop step that kept him mobile and in a good base to absorb a rush at the same time. He used his hands well to extend the speed rushers beyond the quarterback target.
