Overpay for Tank: lose Smith or LVE or Byron Jones, not get an accomplished 1T because your are saving money, get only adequate 3T, and just hope that the pressure you get from the RDE you can keep getting is from a draft pick because if you ever get a good RDE he will demand more money than Tank is demanding because he plays the "position".
Tough decision, but an injured guy with injury history, who didn't show up in the playoffs ----- I know what NE would do, and unfortunately they are the ones that Dallas should be trying to become like.
