(Sorry for being long winded below. I wish I could be concise.)
The Jets have a clause for the $6 million guaranteed that Revis gets this year. Any money a team signs him for goes back to the Jets up to $6 million.
So, for instance, if a team signs him for 1 million, then the Jets pay 5 million and the team pays 1 million.
If a team signs him for 5.9 million, the Jets only pay $100,000.
Let's say last year he was great and was Revis Island, but the Jets wanted to rebuild and cut him anyway. If a team signed him for 9 million, they would pay all 9 million because it exceeds the 6million guarantee.
If we assume his down year and age means no team is going to exceed $6 million, then no team will sign him for more than the minimum. Revis won't care because he gets $6 million and teams have zero motivation to pay more than the minimum.
So at this point, it's pretty much where Revis wants to play. His salary's going to be the same $6 million wherever he goes. Very few teams don't need a good corner, Revis' legal troubles seemingly are behind him, and I'm pretty sure teams would gamble on him being in shape considering it would only cost the minimum.
