This country may be short on greenbacks, but not greenshirts. According to a USA Today survey, 105 players graduated high school early and enrolled at their colleges in time for spring football in 2008, up from just 15 in 2002. Rivals tabbed this year's total at 103, but many expect the final count to surpass the '08 total. The jump start benefits some more than others, however. With that in mind, here are the early enrollees who made the biggest impact this spring.

Shepard was the crown-jewel of LSU's recruiting class, which Rivals.com ranked No. 2 behind Alabama's, and he's lived up to the hype since arriving in Baton Rouge. While the Tigers recruited Shepard as a QB, coach Les Miles has made it clear the dynamic freshman will wear multiple hats for LSU this fall as a versatile offensive threat.
