thats not how new deals work. First off trading Revis is worse for the cap than keeping him. Re-signing him they can drop his 2013 cap number to a minimum and bump the bonus cap hit across several years.
Strictly speaking, for 2013 the best the Jets can do cap-wise is re-sign Revis. I'm not making it up. Ask Jason.
And what are the Jets' chances at a SB this year with Revis? Zero.
