How long can the offensive line hold up?
Pouncey clearly hasn't fully recovered from his ankle, although he did look better than he before when he tried to play and had to come out of the game.
Ramon Foster left the game but jogged off and didn't appear to have any long term problems, hopefully.
Kemoeatu had probably one of his best games of the year, except for the bonehead shove that could have been flagged as a personal foul.
Marcus Gilbert was owned at times again against the Browns, completely whiffing on several oncoming pass rushers. One in particular on a 3rd down play that forced the offense to punt.
Starks is still the best lineman but he's had some issues lately with elite pass rushers. The Broncos will test him and Gilbert both and if they smell blood Ben will be running for his life. Denver is currently 20th in the league in total defense: 18th vs the pass and 22nd vs the run.
Don't let those stats full though, even though they are banged up with key players like Von Miller not 100% and Brian Dawkins suffering from a neck injury they will still get after the Pittsburgh offensive line. If Pouncey can get back on track and the rest of the players can just stay on the field for an entire game they may be ok, but that's a tall order to fill.
