With all due respect, many of your suggestions are not "creating" cap space in 2015 but rather pushing off the cap hit to later years impacting the cap space in those years. The only true way to "create" cap space is to cut player compensation or to cut or trade the player. IMO, if we truly wish to create cap space in 2015 without affecting our ability to sign players in later years, then we have to cut some players and/or player compensation. To me, there are some prime candidates:
1.) Revis- Obviously we can't pay him $20M so its a matter of figuring out what the market will pay and if we see that figure as a value.
2.) Wilfork - 34 year old (next season) is not worth anywhere close to the amount he is contracted. IMO, he needs to take a substantial cut or be cut.
3.) Mayo- That contract needs to be renegotiated.
4.) Solder- Left Tackles don't come cheap but I'm not sure he has played up to his $7 M number
5.) Hooman- just not worth the money
6.) Dennard- I can't see how the organization can pay their 6th CB $1.5M. I think some other team might see value in Dennard although I can't see use getting more than a late round pick for a guy who's under contract for one more year and is on probation.
Obviously this is something you understand but I thought the word "create" didn't accurately reflect all the ways you've suggested to gain more cap space in 2015.
