I think we're going to see some change. How much and when is unknown.
Buch is candidate to be moved. Strome could be a candidate depending on what the Rangers do with Mika and Chytil, and potentially Buch as well.
If the Rangers feel like they want to change the balance up a bit, Buch could very well could for a guy designed to be more of a third line center, with Chytil sliding up to finally man the second line. In that case, Strome is potentially moved for a different roster piece.
Mika is a wildcard right now. I think there's a real possibility the Rangers look to commit to him. But if he goes, they could opt for more of a young center with top six potential rather than a ready to roll third line center.
So there's many variables there. I think we could see two of the four guys you mentioned moved. I think more than probably becomes a bit more turnover and turmoil than they should pursue at present time.
