He's drawn third-round projections after passing for 5,783 yards, 35 touchdowns and 62.2 percent completion rate in his college career, which ended with a torn anterior cruciate ligament he's been rehabbing from.

Boone, a senior, had 44 grabs for 611 yards and eight touchdowns for LSU. It is not expected he will be drafted. All three worked out at LSU's pro day on Wednesday.
