What are the Big East's greenest units?

Posted by ESPN.com's Brian Bennett

It's not easy being green. Especially in college football.

Experience is usually the name of the game in this sport, with the possible exception of a few skill positions like running back and receiver. Still, the team with the most talented upperclassmen is usually going to be a major contender.

With that in mind, and with green our day-long focus here on St. Patrick's Day, here's a quick look at the greenest units on each Big East team:

Cincinnati: Take your pick between the defensive line and linebackers, where no starters return from 2008.

• Connecticut: This is team with a lot of experience, but the receivers -- even the underperforming upperclassmen -- should all be considered green in the new, up-tempo offense.

Louisville: The biggest bunch of newbies are at quarterback, where there are four candidates for the job but not one who's seen any significant playing time at this level.

Pittsburgh: The running backs are all brand spanking new, thanks to the defection of LeSean McCoy and the graduation of Conredge Collins and LaRod Stephens-Howling.

Rutgers: The quarterbacks and the receivers are mostly without experience. At least they can learn together.

South Florida: Look no farther than the offensive line, where four of five starters need to be replaced.

Syracuse: Three of the Orange's top four safeties, including both starters, are gone off of last year's team.

West Virginia: On a mostly otherwise veteran team, the Mountaineers are breaking in three new starters on the offensive line.
