I disagree with the general sentiment of the posts. I actually think this would be a great move? I have no interest in watching my team be a punching bag this season. Jets fans have to have something to look forward to. Right now they are staring down the barrel of a 3-13? 2-14 season? Sorry, but watching that shit does not interest me in the least bit.
There is no strict, say rigid way to rebuild a football team? People think there is, but they are wrong.
Sherman allows the Jets a numbers advantage like Revis used to be. It allows Bowles to do what he wants to do the most - that is blitz. If there's any truth to the claims that the linebackers are great (loud mouths said that, I certainly didn't), acquiring Sherman essentially could catapult this defense into being a finished product. It would give Bowles his best chance to succeed. It would also allow Mac to focus on offense and ST's during the draft.
You know IMO Mac and Toilet are challenged by their jobs. A move like this would make their jobs that much easier and they can use all the help they can get...
