If the Jets are smart they can resign Revis AND create more cap space or just keep the situation the same.
Revis currently counts $9 mil against next season's cap. The Jets can give Revis a huge bonus and divide the cap hit from that over the number of years he is under that contract. i.e. - $30 million bonus for a 6 year deal is $5 mil per year cap hit. Base salary would be only around $3 or $4 mil before being added to the aforementioned dividend of the bonus.
Ofcourse this is JI and any idea that doesn't involve trading picks for Alex Smith is unviersally called stupid but that's just the reality - Jets can keep Revis without going into cap hell.
