Southern California will have a new starting center next season, as Marcus Martin took to Twitter on Friday to announce that he was leaving school to enter the NFL Draft.

Martin began his career as a guard before moving to center this season, and he was named All-Pac-12 First Team this season. However, his decision to enter the NFL Draft is a bit of a surprise, as Martin isn't currently included amongst the center prospects in our 2014 draft position rankings.

Still, he's coming off a very good season, and at 6-foot-3 and 310 pounds, Martin certainly has the size of an NFL lineman. However, interior lineman, particularly centers, aren't as attractive to NFL teams in the draft as offensive tackles are, so it's hard to know where Martin will go in the draft this season.
