I think the Dolphins would be very happy to trade Taylor to the Pats, if they think they are getting back more than he is worth.
If the rumors are true, the Dolphins do not feel he is that valuable to them.
If they could trade him to ANY team for more than he is worth, they would be thinking that they improved their team, and also that the other team got worse. If that were the case why wouldn't you want to trade him to your rival?
If the Pats offer the most and it is enough, the Dolphins will trade him here without hesitation. First, if you think its a good trade, you believe you weaken the opponent, and secondly, if the Dolphins believe Taylor is still a dominant player and are trading him anywway then obviously they are building for the future and really wouldnt care how Taylor affects us immediately.
The REAL question, IMO, is why would the Patriots want to trade for him? The cap hit would be exhorbitant, and not something we could afford along with addressing the rest of our needs, and we would be paying that kind of money, in order to 'upgrade'? over Vrabel and Thomas?
