The controlled environment of the dome should help, but I doubt he cares being from ND, and an outdoors guy.
And what we need from him.... He doesn't need to be top 3, but he needs to be top 10. As said above, we don't have a D to dominate like past game manager teams have had. At the end of the day, there are many many more teams that win the SB with a good QB, than with a game manager. A good to great D helps too.
