From what I gather, Ware's base for 2014 is $12.25M and none of it is guaranteed. So, if he is cut, he gets none of the $12.25M. So, Ware has millions of reasons to consider a pay cut. Ware WILL accept a pay cut unless Jerry Jones does something stupid and restructures Ware again. If Ware is cut, no team is paying him $12M for 2014. His market value is somewhere in the $5-7M/yr range at his age and if healthy imo. Ware can either accept that amount to stay in Dallas, get a trade for a team willing to pay him that amount, or be a June 1st cut (assuming no Dallas restructure).
Like you said, Ware might just say forget it and say restructure or cut. Ware then becomes a FA and can do whatever he wants. So, yeah, maybe there isn't much trade value to a player other teams know will be cut.
It would be nice to trade him, but it looks like it will be a restructure or June 1st cut. I hope it is the cut.
