Interior line prospect coming off of his best season at Texas A&M as a starting center. McCollum is long and high cut, lacking leverage and drive power at the point of attack. He does a good job of locating his hands with proper placement and will activate his play strength to secure blocks as quickly as possible. He's a very average athlete when isolated in pass protection, but should be able to make most blocks in the run game. He has late-round potential and could end up fighting for a roster spot at some point in the future.
