Haynesworth has been pretty quiet this year since the Patriots signed him. He's one of those guys that when he wants to play he's almost unblockable. However he's not exactly lighting up the stat sheet so far in 2011. He's still a concern though for Sean Kugler's group.
Depending on who he lines up against on any given play I would suspect the Steelers will end up having double team or use one of the Tight Ends to chip him. I'm not sold that he's going to completely dominate anybody, not even the Steelers line but they still have to be careful to not let him start teeing off and get in the backfield. Look for Bruce Arians to keep Heath Miller or David Johnson in to help block early on to see how things go. If Pouncey, Foster, and Kemoeatu can handle their own that will allow Ben to use both of his tight ends as weapons in the passing game more often. Playing against an offense like the Patriots you need every available player to make a play but first and foremost the protection of Big Ben has to be solid.
Haynesworth is as strong as an ox and like we said when he wants to play, he can be the best in the business. The line of scrimmage needs to be established for the Steelers and they need to take control of the game from the get go. If Haynesworth starts getting pressure it will be more difficult to stop him as the game goes on because you have to commit extra help which could free up the pass rush from another angle.
