Roethlisburger will remain at a 95 I think, and Leftwich probably will not even be on the roster. Parker's rating seems really low, by at least 5 or 6 points, and Mendenhall's seems a bit high in my opinion. As far as receiver's go, Washington's is probably a little high, only by a few points though, I would put him closer to 80 or possibly an 81. Harrison and Woodley will both be a little higher, especially Woodley. The other LB's seem pretty much spot on to me. Lastly, I think Aaron Smith will be closer to a 90.
In addition, I think Ike Taylor and Townsend will both remain in the high 80's, with a slim possibility of Taylor breaking 90. I also think Hampton will remain in the upper 90's, probably a 96 or 97.
The overall team rating will no doubt rise, probably to at least 91 or 92 to open the year.
