Because he sucks as a QB. I don't care he is a great guy, works hard, comes in first, leaves last blah blah blah. Bottom line, he isn't a good QB. He is nothing more than "Rudy". Loveable guy you want to root for, but just isn't good.
Way past time to get a Real QB in here. BTW this is TT's 7th year? Goff is just starting his 2nd and can all ready do this...
