You've named a whole bunch of kids who have a lot of potential and have contributed meaningfully, but don't have huge resumes. In all fairness, I expect some of them will when their time on the 40 is done. Some of Colt McCoy's teammates at Texas:

I mean, just for reference. It's not like Colt was surrounded by a bunch of bozos.
Also, in my 20+ year career as a civil trial lawyer and briefly as a judge and mediator, it's been my experience whenever someone uses words like "inarguably" they actually mean "arguably but don't argue with me." Not saying, just saying.
