Age, and experience matter and can't be coached.
Shouldn't be an excuse or a reason three years into a coach's tenure.  Sorry.  
It doesn't matter how well any of the rest of that team ages or improves.  Without a quarterback who can at least occasionally make a throw?  We're fucked like one of RWS' goats.  
We start next year with Trotsley under center?  Fucked.  
We start the year with a green-ass freshman under center?  Fucked. 
Agree that we better find a juco kid or somebody who desperately wants to transfer.  Fuck, does Brent Schaeffer or Jeremiah Masoli have any eligibility left?
