The awesome college football site The Wiz of Odds (a must bookmark for any college fan) has the schedule posters put out by pretty much every team. They are all fairly standard, using some phrase to sum up the team and featuring key returning players. There's not much skin evident, though Duke (photo below) shows six players in tight undergear. My favorite so far is Florida State (also below).
