Sorry. Not very good at posting links. I saw this retweeted on twitter. It is Coach Pagano talking to one of USC players. I believe the player with the pony tail is Center Khaled Holmes. He actually gets pretty good reviews on NFL.com.
CBS sports draft profile grades him out as a 4th round pick. Looks like he played Center and Guard also. Sounds like he has got a bit of a tenacious nasty streak him according to his review on NFL.com.
