I like that Stanley has a couple year gap between the guys he is competing with. I agree that its most likely he gets put on the practice squad this year, but maybe he wins the back-up role due to cap cuts for the more veteran guys. Stanley is a very cheap back-up QB right now.
I do not see Nate ever being a starter, same with CJ. But, the key is getting to a second contract. If you do, you can be a back-up in this league for a decade or more. Look at Chase Daniels. Stanley has all the tools, and maybe with a year to develop, he can be as good as what Minny has now and win the job cause he is getting paid nothing.
