None of those guys are even as good as Colt McCoy, so I would respectfully disagree with your assessment that next year's draft is deep in QBs. Oh, certainly there are a number of them that will be available....but they are all costume jewelry. No real gems.
FWIW, 3 of those guys are in NFL.COM's 2013 top 10 for all players...Most of them are "prototypes", being 6'3" - 6'5" range. They are pretty highly regarded right now...
5 of them have played in pro-style systems...With 5 step drops, pro terminology, snap counts and huddles
...And none of them are 30.
