Just heard a report on WFAN radio that Nnamdi "is not basing his decision solely on money, he wants to win a Super Bowl".
This eliminates Dallas.
The Jets have the cap advantage, they're restructured a ton of players and released some just to get Nnamdi. They're let some good players like Brad Smith (and maybe Braylon Edwards) go to other teams so save cap space.
Dallas had to make a ton of cuts just to get down TO the ceiling. I don't think they can beat the Jets' offer.
