It's not a pay cut, it's a restructure that's already been built into the contract, or at least was for last season, not sure if the automatic version is still there or not. The problem with a restructure is that it just pushes the money down the road, for instance you could turn 6 of a player's 8 million dollar salary into a signing bonus, which means he still gets all of the money this year and would save $4 million v the cap this year, but that money then gets pushed against future years and makes those cap hits bigger, and also becomes money that will count against the cap if the player is released.
I'm not sure if Sanders contract can be restructured, it depends how the extension was done, but it's difficult to restructure new contracts and there are rules against restructuring twice in one year. But again I'm not fully sure how that works.
But I wouldn't expect either to take a paycut, so if that's what you're thinking, it's not going to happen.
