A guy with a bass
While I disagree I can understand your point. I think an extra year in the KHL isn't going to hinder his development.
I don't think it would hinder his development so much as I don't think it would help it as much as staying in NA.
Also, the Rangers very much need to point out the example to him of Bereglazov. The guy went back to the KHL and missed out on what would have been his chance in the NHL later in the season. And not all that much later than him going back.
