Hard no, but points for creativity.
Tarasenko has had injury problems, but when he’s healthy he’s as lethal as anybody in the league, and he’s a big body that has come into his own as a 200-foot player. As well as we’ve been playing, I’ve missed the hell out of that guy this year. I would be very sad to see him go so unceremoniously, even for what is (as you propose) a more-than-fair package.
The only way I even start to consider something like that - and even still I’m very, very far away from being willing to part with the most exciting Blue since Hull - is if we’re also getting Puljujarvi in a separate deal. Loading up with two huge, skilled wingers who can grow together with our centers would be very appealing and exciting. But I’d have a real hard time watching Tarasenko in anything other than a Blues jersey. Turning a guy at the tail-end of his peak years as he’s starting to get injury troubles into two/three high-value, young replacements would soften the blow, but it’s still not something we would probably do if our goal is to win more Cups in the next few years.
It would be fun as heck to go through that though. Lots of drama!
