What offense?
Thats part of the reason why they got him. Something is obviously wrong within the Jets org. Many people are starting to say that it should be the GM who gets fired, instead of Rex.
Gino Smith is the GM's guy. Rex hinted that he doesn't even have sole say to be able to replace his quarterback.
This deal for Harvin, might be the GM trying to cover his ass.
If they still lose, then he can say "Hey I got you a playmaker and you still lost".
The Jets have talent, its the front office that is bringing the org. down.
