The biggest unintended consequence of resting our starters was helping the Jets get in. If not for that, I think it would be the Steelers who we would getting ready to play now (assuming they won a couple playoff games too of course). I would be much more scared of them. With Polamalu playing, they would be a real tough team to beat. Granted, their talent isn't where it's been in recent years, but the experience and QB is so much higher than the Jets.
Just a thought
(of course I could be wrong and maybe it'd be the Texans. Also scary b/c they always play us close, but not quite as scary as the Steelers)
