If you're sure about anything in the NFL, just wait a few weeks. Heck, if you were sure about anything from Week 7's Giants-Broncos game, waiting a few minutes seemed to work just as well.
After six months of waiting for the NFL to return over the offseason, what we see in the first few weeks of action feels stickier and more meaningful than anything else, and we form opinions quickly.
Of course, we should know that what happens in September doesn't always mean very much by the time we get to the postseason.
