Cal C Ryan Kalil may be the best center prospect of the last few years, even better than Nick Mangold last year. He surprisingly has added almost 15 pounds since the season ended, checking in at 296 pounds today. He still ran a speedy 4.96 forty.

NFLN's Mike Mayock and Dick Vermeil wonder why Kalil bother adding the weight. He's a technician and isn't going to play for a team that wants a mauler. Either way, he's probably a first round pick.

Mayock comes with another good scouting term: a guy that can only "play in a phone booth."
