Count me in as one that thinks Mariota is overhyped. Do not want at all. Would take Petty and Hundley over him.
As long as he wasn't carted off the field, he'll probably be fine. I would only be worried if the injury had something to do with his groin.
That was my initial reaction - that he had reinjured it. As it is, he looks like he may have earned himself some time off until game 1. Suits me fine.
