As this college football season winds down, the Trojans must turn a hopeful eye to next year, when they hope to wash away the stain of a disappointing 2012 campaign.
In order to do this, USC must replace some very important players whose eligibility has run its course.
Fortunately for the Trojans, they have a fairly young team and many starters will be returning for the 2013 season, but the holes to fill are large ones, and the challenge for head coach Lane Kiffin and his staff will be to find replacements that can take USC where they hoped to be in 2012.
This slideshow will look at these players who will be leaving the Trojans after this year and offer a glimpse as to who their replacements might be.
The list contained within is organized on the basis of player importance, and the criteria used to arrange it is predicated on the player's overall value to the team and how difficult it will be to replace them.
Next year will be critical for Kiffin if he hopes to retain his job going forward, and the decisions to fill these holes in 2013 may very well be the difference between his coaching the Trojans in 2014 and USC finding a new man to lead the program.
So without further delay, here are the roster spots that must find exceptional replacements for next year.
Note: This list does not include juniors who may or may not declare for the NFL draft.
