Well, I like the fact that you are skeptical Zach.
In the world of sports, if you want to win, you have to prove it. The fact is: Paul Johnson has entered a new league. I agree with your skepticism and I myself am not SURE that PJ will be an annual winner. However, I do feel he has proven himself as an offensive mind and a coach that can get great results (D2 championships with GSU) and also get the most of lesser athletes (Hawaii and Navy).
This combination of achievements leads me to believe that PJ can and will make GT a good football team that we can be proud of.
Edit: I just noticed I was misspelling your name, Zack. I apologize.
