Although I am a fan of tagging Cassel and trading him, I am unsure how this tactic affects the Pats ability to go after free agents, namely a shut down CB. Questions I have: How much cap space do the Pats have heading into 2009? Would they have to cut players to get under the cap at the start of FA if they tag Cassel? Would the Pats have enough money to sign a shut down CB early in FA with the tag applied to Cassel? What happens if Cassel signs the franchise tag tender contract? Can the Pats revoke the contract if they are trying to facilitate a trade?
