You're standing on my neck
I've always thought the Jets failed to properly use Keller. Whether by preference or incompetence, it just felt like Keller didn't get the ball as much as he should've. Either way, it makes me doubt they would even consider taking an early TE, especially considering all the holes they have.
I highly doubt this helps the Dolphins in any way, but I suppose it's possible if someone thinks the Jets will take a player they want more than they thought the Bucs would. (Assuming you agree that trading down is good for the phins).
Either way, this is a great deal for the Jets since they wouldn't have been able to retain Revis after this year (a rebuliding year) anyway.
Not every human is a manipulative, opportunistic, letch... or at least that's what I'm told.
