Wrong place but I'll help you out...
LT in the NFL? Right now I'd say no, but with time Sanders could develop into a LT. I think he might start off inside or at RT.
Serviceable as best if a team drafts him to start at LT right away, he struggled at the Senior Bowl.
Charles Brown from USC my fav comparison, both 2nd round value with potential to be LT's in the NFL one day. Both aren't very strong in the run game, but has shown the ability to protect the QB.
