The strength of a particular NFL draft class will always primarily depend on which top underclassmen prospects choose to declare.
The 2014 draft class is no different.
Many of the 2014 class' big-name headliners are underclassmen prospects such as Louisville quarterback Teddy Bridgewater, Oregon quarterback Marcus Mariota and South Carolina defensive end Jadeveon Clowney.
Still, this year's group of senior prospects seems to be unusually strong, even though the group experienced plenty of defectors when a record number of underclassmen opted to declare for the 2013 draft. Fortunately, premier prospects such as UCLA linebacker Anthony Barr, Texas A&M offensive tackle Jake Matthews and Michigan offensive tackle Taylor Lewan all bypassed the chance to be first-round picks in the 2013 draft in order to return to school for one last year.
Seniors like Barr, Matthews and Lewan are all cream-of-the-crop prospects, who appear destined to be high picks in the 2014 draft. However, there are plenty of other seniors who belong in the first-round conversation as well.
As the 2013 college football regular season now heads into the home stretch, this is a good time to assess the stock of the sport's top senior prospects.
Though a lot is bound to change between now and May 8, here's a look at how I feel the top 25 overall senior prospects stack up at this point in time, along with rankings for the top 25 senior prospects at each individual position.
