If he were such a crap OC, why did McDermott hire him to begin with . . . .
In any event, I asked a question and no one seems to know the substantive reason why he was fired other than people guessing like yourself.
As an aside, I remember when McDermott was hired and fired the Bills' priest/minister. I suppose if I asked you why he was fired, you probably would say that he was a "crap" priest/minister.
God bless.
