Jets should still sign Leonhard if/when he's healthy
The dude is a football player. Leonhard can still be an improvement for the defense in the nickel/dime package. Landry and Eric Smith aren't exactly world-beaters in coverage. And we could really use his communication skills. He plays a role on special teams too. You can plug in anywhere on specials and he'll do it. Also now that Cotchery is gone, he's the only one who can catch a punt without making a mistake on this whole team.
The market for him is not likely to be expensive. Not many teams want an undersized safety coming off back-to-back season ending leg surgeries. The one thing I can see is Belichick signing him because we all know that secondary is atrocious and can use a guy with a brain like Leonhard.
