I don't think they are "that" hurt at all, but it is a difference of opinion I suppose. No big deal.
I am quite sure that Redman will do just fine, and that the loss of Mendenhall is really not that big of a deal at a position of depth like RB.
Pouncey will rest this week against a lesser opponent. Obviously he would like to play, but I would say it's safe to say that he'll be okay next weekend.
Ben's injury is not that severe at all, as he has been a FULL participant in practice; don't get lulled into the whole Roethlisberger is 'hobbled' saga. He may be in some pain, and even somewhat limited in moving around/scrambling, but he admittedly "felt real good" just last week.
His aggrevation of the high ankle sprain will have plenty of time to heal, and it makes you wonder if Brady's broken/fractured foot last yr was WAY worse than drama queen Ben's...
Ryan Clark is basically just taking the week off, isn't hurt in the slightest, and will be well rested for next weekend.

Stating that they are "really hurt" is a stretch...they aren't really hurt until they are using WR's in their secondary...and down to their 3rd and 4th string centers (not their backup center).
This whole Steelers being hurt thing is almost comical. They are a little banged up, but starting everyone except Pouncey and they had to place a player (Mendenhall) on IR. BOO HOO!!!
Do you really think that Mewelde Moore would have seen many touches, if at all? Clay is another bruiser, did very well at WISC last yr, and will be just fine blocking for Redman and taking some goal line reps/late game reps.
