If Carter is traded it will be for a lot less than most of you are proposing.
That is why I mentioned earlier that most would say my proposal is not enough. I think Oiler fans (especially on the boards) overvalue our players while on winning streaks and undervalue them (heavily!) while on losing streaks. People don't take into account that the individual player is not the team. I think that players like Cogliano are still highly regarded, and Gilbert is not going to be evaluated by a GM solely on his play these past 2-3 months.
Carter will go for a first/second line player and a prospect most likely, which, if you balance things out (Gilbert being 2-4 defenseman on most teams, Cogliano on 2nd line next year on maybe close to half the teams), is what I proposed.
