Foles was pretty inspiring in his 2nd season, wasn't he? Dude proved that season that he can definitely play in the NFL.
Hundley? He sucked in the preseason, but it was clear as day to everyone other than Thompson and McCarthy (and maybe Tex) after 3 games and 2 starts that Hundley couldn't - and still can't -play. Thompson should've signed Kap. McCarthy pretty much simplified the offense for Hundley, a 3rd year player playing like the rookie Kizer. No reason he couldn't do the same for Kap til Kap got familiar with the playbook.
If not Kap, Flynn was sitting at home all day last fall annoying the shit out of his hot wife. Flynn knows McCarthy's playbook like the back of his hand. After a couple of warm up throws, and despite his noodle-arm, Flynn would've been more accurate than The Hun.
Hundley might make a good coach someday, given his team-first attitude, but he can't play in the NFL. He's not even a good backup.
