POSITIVES

—Experienced, consistent lineman with reps at center and left tackle for Michigan.

—Four-year starter for the Wolverines and the first true freshman tackle to ever start the season opener.

—Has the strength to anchor against power and uses angles well to seal off inside moves.

—Fires off the ball low and with good pop in his pads to push the run game.

—Has shown the mobility to move down the line of scrimmage and has lateral skills.

—Smart and durable, and is a worker, according to coaches.

NEGATIVES

—Short-armed at 32 ⅛", which cements his projection as a center despite experience at tackle.

—Average athletic traits show up on tape against quicker defensive tackles or when asked to reach a linebacker.

—Balance looks poor when asked to seal off a defender on the move.

—Failed to develop at Michigan and looks maxed out physically and in terms of technique.

—Hands miss wildly at times.

OVERALL

Two years ago, scouts were talking about Mason Cole as a potential Round 1 player if he continued to develop. That didn't happen, but Cole is still seen as a reliable asset at center. He's a good fit in both zone and power schemes and could be starting early in his pro career.

GRADE: 5.80 (Round 4)
