How to get to six

LOS ANGELES -- After witnessing the formation of the new Pac-12 conference, rooting down the stretch as the Trojans finished off a 10-win season, and watching Matt Barkley and Robert Woods set school and conference statistical records, this past season had the unmistakable feel of a math lesson for USC fans.

But class isn't dismissed quite yet, as the numbers game increases in intensity as signing day draws nearer. It has been anticipated for months that there would be some roster juggling by the USC coaches, as the NCAA imposed limit of 75 scholarship players goes into effect this season. In order to take a full class of 15 players, there would need to be some defections from last season's roster. It is disappointing for coaches, players and fans alike, but it is the reality of the situation.

WeAreSC provides a look at how many available spots remain in this recruiting class, and what that means for the roster.
