Stanford's Andrew Luck left a year early for the NFL. USC's Matt Barkley returned for his senior season. Baylor's Robert Griffin III bolted. Oklahoma's Landry Jones stayed. Alabama's Trent Richardson moved on. Wisconsin's Montee Ball is still in Madison.
The top six finishers in the Heisman Trophy vote were all underclassmen. The top three left early (Griffin, Luck and Richardson). But the next three came back (Ball, Tyrann Mathieu and Barkley, though Mathieu was given the boot from LSU).
On the defensive side of things, while superstars such as LSU's Morris Claiborne, Mississippi State's Fletcher Cox and Alabama's Dont'a Hightower entered the draft early, others, such as LSU's Sam Montgomery, Utah's Star Lotulelei and Notre Dame's Manti Te'o, came back.
Bottom line: There's a lot of star power returning to college football in 2012. More, perhaps, than usual. Each player has his own reasons for coming back, though visions of national championships, individual awards and, yes, better NFL draft position certainly danced in their heads.
