Last season, Andrew Luck shocked the country when he announced that he would stay at Stanford for another season even though he was guaranteed to be the No.1 pick in the draft.
That decision has hurt underclassmen in the past (i.e., Jake Locker, who was slotted in as the No. 1 overall pick two seasons ago but decided to stay at Washington for another season).
This season, it is Matt Barkley's turn to make the tough decision. The junior has come on strong late in the season and has likely put himself in the mix to be a Top 10 pick—but with USC's postseason ban lifted next season and all the young talent on the Trojans squad, Barkley may choose to return to chase the BCS National Championship.
Some underclassmen will ultimately return to school for another season, but others will see the potential to make millions in the NFL and forgo their eligibility as an amateur athlete.
