"If he hasn’t already, I think Armstrong will gauge the interest around the league. He has to. Tarasenko has two years left on his contract, and with a $7.5 million cap hit, the Blues need production out of that position at that cost. Some might say that Tarasenko will be OK when he gets more games under his belt following his third shoulder surgery, and they may be right. But from a team-dynamic perspective — the desire to suit up a blue-collar, hardworking lineup — the Blues may feel the need to go in a different direction, and Tarasenko may want that, too.
As far as his declining value, it is what it is. I don’t know that Tarasenko is going to score 35 goals next year and reraise his stock. So at this point, with Armstrong saying the championship window is still open, he has to decide “Can Tarasenko help this team?” And if the GM doesn’t think he can, then he needs to find a “hockey trade” because the Blues would benefit tremendously from player(s) at $7.5 million in cap space who can either score or play within the system. Tarasenko does have a no-trade clause, so he has some control."
