In my opinion, Rakeem Cato continues to be dreadfully underrated.
I have watched him play quite a few times. He could definitely be a serviceable NFL QB. IMHO, he is better than the garbage that is being touted as top picks like Winston, Mariota, and Hundley.
I think Cato could be a bit better than Leftwich was coming out of Marshall. Not as good as Pennington, but not bad either. He is a good QB.
