It didnt get alot of notoriety, but there was a blurb the other day that said not only were the Cowboys negotiating a long term deal with Spencer, but they had told Spencer's agent he was free to negotiate with other teams on a long term deal for Spencer too.
He gets a chance to get the best deal possible for himself, then if the Cowboys cant match the deal they could work out a trade with that particular team. Compensation probably wouldnt be an issue, as at that point the Cowboys would be happy to get something in return for a guy they couldnt have re-signed anyway. I think its likely we could get a 3rd rd pick or depending on how bad somebody wanted him, maybe a 2nd.
