There are many layers to this subject that need to be explored. But here are some immediate thoughts that come to mind.
You always start by following the money trail. And from that perspective, this is not a surprise. Revis will make $6 million in the final year of his contract. The Jets are approximately $19 million over the cap and need to slash salary. On top of that, if Revis returns to form, he could command one of the NFL's most expensive contracts in 2014. The Jets are rebuilding and might no longer be an attractive option for Revis, who surely will have many suitors. It's probably wise for the Jets to see what they can get for Revis right now, as opposed to losing him to free agency next year without any compensation.
Speaking of compensation, what can the Jets get in return for Revis? It certainly won't be market value after a season-ending knee injury. Teams will be nervous about trading too much for Revis without knowing whether he can return to Pro Bowl form. The Jets must try to sell low for the best cornerback in football. But as we mentioned earlier, the Jets are rebuilding next year, and it's best to get something.
Finally, what does this mean for Jets coach Rex Ryan? He is entering next season in the hot seat after back-to-back non-winning seasons. Ryan needs to win now and cannot be happy that his owner wants to trade away his best player. Without a quarterback, without much talent on offense and with the potential loss of Revis, Ryan could be put in a position to fail. The Jets are clearly starting over in 2013, and if Ryan does not win enough during this rebuild, he probably won't make it beyond next season.
