I think they need to move Letang. Sure he is far and above our best D man but I believe a team like EDM would overpay for his services. Edmonton would never land a Defensemen of his caliber in UFA.
7.25 for a D that cannot run the powerplay and is not an elite shutdown defensemen is madness. Especially one that is injury prone. You cannot pay 7.25 for great intangibles when you are already paying Crosby, Malkin, Kessel, and Fleury.
Does losing Letang immediately make us less likely to win this year? Sure, but this year is already looking dim.
Get Crosby some solid wingers, play our young puck moving defensemen, and see what happens.
