Doing whatever he wants? If a rule or by-law was broken by Coach Sanderson, Coach Manning would have a point. None have been.
There's probably a lot of frustration on his (Manning's) part, as Wilson did have a have a good case for an at large compared to others - similar to some universities and their situations of not receiving bids to the NCAA basketball tournament. Deserving parties are commonly overlooked.
It happens.
Side note, it's funny to see how much Cael Sanderson lives in other coaches heads. Manning's projection and whining is just another example.
