I don't understand how anyone can make the bold statement Mariotta will be an NFL bust based on one game where his offensive line didn't do the job. He has the arm, brains and presence. How many full games have you seen him play? One, last night? His numbers were still good while he tried to do it all himself.
The biggest problem Mariotta and Winston are going to have at the next level is being drafted by rudderless 2-14 teams in freefall and fans expecting them to be saviors.
