That may be the market now, but markets change.
I don't think ADA is very weak at one side of the game. He is not great in his own end. Trouba is not great in the offensive end or getting out of his own end. I think it was Trouba who turned the puck over at his own blue line just before ADA was turnstiled to end the 3 game playin. Girardi and Staal were bad in the O zone and bad at moving the puck anywhere and the Rangers spent a ton on them while making the playoffs, even the cup finals.
Lundkvist has not played in N America, he looks very promising. He is likely to need some AHL time. If not it's possible we have the same conversation about him as we do with Chyitl. Lias, Howden in terms of whether or not they could have used more AHL time before being placed on the NHL roster.
Rangers have time to make the right moves, just because they made cap space buying out a player and attaching a future to another to trade him does not mean they should use all that up on players who just happen to be on the market.
