I watched the film again last night and focused on the right side of the line. He's an improvement over Glowinski but not by much. He's very big, but slow footed, leans too much, top-heavy, and didn't really generate much push in the run game despite his size. He's going to be eaten alive the first game where he lines up across from somebody you've heard before.
Of course, I hope I'm 100% wrong and eat my words, but he looks like a temporary fix at best. We have no NFL-caliber guards on the team right now.
