They said he would compete at LG because he played on the left side in college. Easier to transition to LG from LT than to RG from LT.
Well hangman can barely move anymore and Silatolu is fairly mobile. Cam is going to be running option reads to his right (throwing side) so you want a guard that can pull ahead of him.
So for anyone confused by what I mean, imagine DeAngelo lined up to the left of Cam in the pistol/shotgun. Ball snapped, Deangelo breaks right to take the handoff for a sweep. Silatolu is going to pull out and run to the right to either seal and edge or get to the second level.
Cam can then read the defense (specifically what the DE is doing, and either let DeAngelo take the handoff, keep it himself and roll out to the left if the DE crashed in, or pull it back and follow DeAngelo to the right where he can do whatever he wants.
The more videos I watch of this guy the funnier it gets when he just throws his man to the ground after every play for absolutely no reason.
