Of the top CFB recruits All-Time:

Drafted in NFL Draft (5): Rashan Gary, Robert Nkemdiche, Jadeveon Clowney, Ernie Sims and Vince Young

Won NCAA Championship (1): Vince Young

Made Pro-Bowl in NFL (2): Jadeveon Clowney 3x and Vince Young 2x

Currently on a NFL roster (2): Rashan Gary and Jadeveon Clowney

The top CFB recruits of all time had unsuccessful post-college careers. Only 2/5 are currently on NFL rosters, and only 1/5 is a starter (Jadeveon Clowney). Only 2 made the pro bowl. One silver lining, regardless of the failure to make successful careers in the NFL, all 5 were 1st round draft picks in their respective years.
