Pete Carroll has had a busy few weeks at USC.When he hasn’t been busy locking in another stellar recruiting class for the Trojans, or getting castigated for speaking his mind about outgoing quarterback Mark Sanchez, he’s been filling massive voids on his coaching staff, which look to be finally complete, after new offensive coordinator Jeremy Bates replaced coach Carl Smith, who left the job he took with the Trojans for the Cleveland Browns, less than two weeks after agreeing with the Trojans.Replacing both coordinators (your offensive coordinator twice), finding a new defensive line coach, promoting your linebackers coach, cutting your Hawaiian vacation short to watch your starting quarterback leave school early, all before jetting out to the presidential inauguration?It’s no wonder that many consider Carroll the hardest working coach in America.He’s even found time to twitter about it.
