I say bring him back for 1 more year. Keep the 3 headed monster in tact but reduce Barber's role to mainly the closer. If he flourished in that role, maybe you keep him. If his production continues to diminish, you cut him after next season when there may be another salary cap in place and cutting him may actually save cap space at that point. The only reason to for him not to be Cowboy next year, when there is no cap, is if somebody is willing to overpay for him. If nothing else keep him around until someone's starter goes down in training camp or preseason.
