Grothe is definatley back at Parramatta next year.
Luke Phillips is retired, but i guess he would still fall under this years contract.
Since he's retired due to injury I think you'll find that he is NOT included in the cap. You need to consider that a lot of these blokes have been at the Roosters long term and have been nurtured by the club into being top-liners. Lomu, Flanno, Crocker, Mini, Toddy & Heggs for example. Flanno re-signed long term before he was a SOO rep. Walker was picked up for next to nothing, while Cayless, Robinson, Fitzgibbon & Catic weren't getting a start at their clubs and were either bench players or reserve graders.
The tired old Roosters must be over the cap rumours have been found to be baseless and have seen lots of rugby league forums go to the great forum in the sky. If you have substantial evidence to support these claims, provide it to the NRL so they can investigate it further. Starting rumours like these can only shut down the few avenues for this type of discussion we have left.
I guess it's up to you...
By the way, have you done the sums on the Knights and the Broncos?
