I feel confident stating Lundkvist will clearly be a better player than McDonagh in his prime and it won't be close. McDonagh does not have much of an offensive game. He had that one fluke offensive run in the long playoff run the Rangers had. That was it. Lundkvist from a scouting report I read also can lay some pretty good hits. If he can keep his speed and bulk up to about 190-195, he should be a two way force out there. The kid is going to be special. Where he was drafted in the first round doesn't matter. Look at the 2015 draft for example. How the heck did Kyle Connor slip to 17? What were scouts looking at? The fact is that the Rangers used that pick from the McDonagh deal to steal this kid at 28.
As far as Miller. He was easily one of the worst playoff players in a Rangers uniform I've ever seen. 41 playoff games, 1 g and 16 points. That sucks beyond belief. The Rangers were a team that was making the playoffs every year there for a while. Miller was a playoff liability and he wanted a huge raise. No thanks. One poster who wanted to not make draft picks a part of this deal, that is beyond absurd. They are a huge part of the trade. In the end it's how many good players the Rangers got back in this deal and what some of them might bring in return if they are dealt. It's who eventually will get the best player. I believe the Rangers got the best player in this deal in Lundkvist. One, because of how many years left they will have him. Two, because they will have him for cheap for a while. Three, because his talent level and level of play will be greater than McDonagh's or Miller's in the long term. It's a matter of whether you believe Lundkvist will be that good or not. Howden has a chance to be a pretty good role player. Hajek has a chance to be a good NHL defenseman or at least a piece to bring in a good player. Gorton got rid of 2 players who simply weren't worth the money they were asking. McDonagh because of his age and minimal offensive skills. Miller because of his bonehead plays, terrible playoff performances and his ability to not handle playing in a city with a lot going on.
People who dump on Howden need to remember this. Nobody was kissing Stephane Matteau's butt in the Rangers fan base. A 6'3+, 220 lb role player who was basically a 30 point forward. In 1994 to now, they kiss his butt and we all know why. Howeden doesn't have to be 50 point guy. Those 6'3, hard to play against role players who drive the net have a way of making big plays in the biggest games of the season.
