This is a good deal for both teams because it serves a purpose for both sides. For the Blues, Buchnevich is a nice addition for a team that is expected to trade fellow Russian winger Vladimir Tarasenko at some point this off-season. Look for Buchnevich to play in all situations in 2021-22. He is a restricted free agent.

For the Rangers, who are trying to reshape the roster, this move makes sense. More moves are expected, and negotiations with Buchnevich's agent may have been difficult this off-season. So, they shipped him to St. Louis for Blais (who can play up and down the lineup on either wing) plus a second-rounder in '22.

Buchnevich's fantasy value should remain solid in St. Louis. Meanwhile, Blais could be used all over the lineup in New York, so he remains a fantasy wild card.
