That's not entirely relevant, is it? The Buccaneers have a good pass defense and Foles carved it up. It was an impressive performance, regardless of whether the Bucs were 5-0 or 0-5.
The record? No not at all. But after 6 weeks it is at least somewhat indicative of the quality of opponent. Tampa may have an alright secondary, but they got next to no pressure on Foles. There isn't a quarterback in the league who won't find some success if you give him McCoy, Jackson and unlimited time in the pocket.
Now, I am speaking from ignorance as I unfortunately missed the games on Sunday and have not had a chance to go back and watch that one. He may have been incredible. But I'll wait to put him in the same discussion as Luck and Wilson until he at least beats a team who has shown the ability to beat other NFL teams.
Know who was awesome against shitty teams? Josh Freeman.
