South Carolina defensive end Jadeveon Clowney and Texas A&M quarterback Johnny Manziel headline a record number of underclassmen entering the NFL draft heading into Wednesday night's deadline.
At least 90 players who had college eligibility remaining are expected to enter the draft, shattering last year's record number of 74.
ESPN analyst Mel Kiper Jr. released a mock draft Wednesday in which 23 of the 32 first-round picks were early entries. Kiper had Manziel going first overall. Clowney, UCF quarterback Blake Bortles and Clemson wide receiver Sammy Watkins were his top-five picks. NFL Network draft analyst Daniel Jeremiah's list of the top 50 draft prospects includes early entries in the top three spots: Clowney at No. 1, Watkins at No. 2 and Auburn offensive tackle Greg Robinson at No. 3.
