Don't care about the value. We don't know that Mac will contribute right away, and while we wait for him to become a "superstar", Lundqvist could be out of his prime. No thanks to trading our #1C and #1D for a draft pick, no matter how high
If they won't trade the first overall for Letang, they sure aren't going to for McDonagh.
Letang supposedly wants Doughty-esque money at least 7m maybe 8.
Currently has only next season under contract.
Too much to give up.
Also Letang is a great overall D on the strength of his skating = offense.
He is not a great pure D on defensive technique.
He has more than enough to get the job done, and he is helped out by playing for a team that generates a LOT of offense.
But if he had to really play really sharp D, we'd see a different Letang, I'd wager.
