Having Surtain around for only one more year would be the worst case scenario. Heck, I rather trade him for a 4th rounder.
We WONT RESIGN HIM! Meaning next year, he walks for FREE! We dont have the cap space to resign him and we are already very deep at the CB position and really dont need him. Plus we need the cap space this year.
Personally, I think if we dont trade him, we just flat out release him. Theres no point in keeping him around for only one year at his high salary if he isnt in future plans. He would just hinder the development of Poole or Howard.
For the future of this team, releasing Pat or trading him is the best move.
