I'm not sure you understand. If Trent goes pro after 3 years, it has nothing to do with him PLAYING 3 years. After 3 years ON CAMPUS he can go pro. Sure, we could afford to redshirt him, but then we risk only having him actually play 2 years. Follow me?
I'll add. If Upchurch's injury effects him in the Spring or next year, Richardson would probably be our #3 guy. At how often we run, Coffee or Ingram could easily pick up an injury as well. If everyone stays healthy this is my prediction at the 3 deep the next couple years:
2009:
Coffee, Ingram, Richardson
2010:
Richardson, Ingram, Matchett
2011:
Richardson, Ingram, Matchett
One thing to remember is that Coffee has been good behind a great offensive line. If our line struggles next year, Saban may use a guy like Trent a little more often because he has the ability to make his own yards.
