He is the better qb, because he is the better qb. He still isn't what I consider to be a "good" qb, but he is better than Mariota. None of this is based on last night, this is their careers.
Once again, listening to national sports shows, they trashed Mariota and praised Tannehill. Only people defending Mariota are the same 5 people who will go down to the last breath defending him.
Good news is, the same homers will be creaming all over themselves about the next starting qb we have and forget all about Mariota.
