Jets proved they can have a strong defense without Revis. His stock went WAY down this season. Had he played, how many more games would the Jets have won? I'd say maybe 1 at the most. Not very different.
On defense the Jets need a pass rusher. The secondary can hold its own (resign Landry first).
If you trade Revis for 2 high picks (a 1 and a 2), then it's worth it.
Revis isn't Brady, who changes the game. Not even close.
