I didn't like bringing Trouba in at that price and term when the deal happened. He is a very limited player in the sense that, IMO, he doesn't think the game very well. Yes, he is physical, but on too many occasions, it is either chasing a hit or after giving up a good scoring chance.
The thought that GM's would be lining up for the same deal that the Rangers got from the Jets is laughable. IMO, it was a deal based on the organization getting impatient. They are in a rebuild. Why not give Ryan Graves the shot? He can do most of what Trouba can, without the kings ransom.
Bottom line is that Trouba is a #2 at best, maybe a really good #3, being paid like a #1. I wouldn't expect much more from him next season. His toolkit is limited.
