I know this was based on those two eras but I took a stab at an all-time App State team.

Some names who came very close for me such as Sam Martin, Joe Parker, Mark Royals, Jalin Moore, Kevin Richardson, Mark LeGree, Rico Mack, Marques Murrell, Scott Kadlub, DaVon Fowlkes, Rick Beasley, Daniel Kilgore, Kerry Brown, Ryan Neuzil, Wayne Smith, DJ Smith, Demetrius McCray, Larry Harbin, Jalen Virgil as a return man, and Josh Jeffries.
I believe every one of these guys played in the NFL, or will play in the NFL, except for Hannon and Clark. Hannon was just too small while Clark was going to be a top 3-4 round draft pick if not for his back issues.
