This year, 98 underclassmen declared for the 2014 NFL draft. That number set a record, crushing the previous high of 73 last year.
While some of them will be obvious top picks, such as Teddy Bridgewater, Jadeveon Clowney and Johnny Manziel, there are only 256 draft picks. As a result, some of those underclassmen that declared will be selected late in the draft, if they are at all.
Likewise, there are players who could be top-100 picks, but could have further developed their talents in college next year, turning them into a surefire first-round talent.
In both cases, declaring this early hurt their chances in the NFL, whether it's due to a much later draft selection costing them money or simply not being ready for the game at the professional level.
