Sullivan is your prototypical tackle prospect with great feet, length/arm length and packs a punch when blocking in the run game. He can quickly snap out of his stance with a strong and consistent base while winning with inside leverage and running his feet off the ball while also showing he can get to the second level to cutoff scraping linebackers and is seemingly very comfortable in space getting a hat on a hat. He stays patient with his eyes and hands in pass protection and does a good job creating a pocket from the edge and is able to win against both speed and power rushers. He should fit very nicely as a true tackle in college and is another prospect that is going to be a nice steal for a college team.
