I could see the Blues taking the above Tarasenko trade, for sure. He's 26 and about to break 30 goals for the fourth straight year, so that's an interesting possibility for Washington.
https://www.hockey-reference.com/players/t/tarasvl01.html On the down side, he starts 68% of his shifts in the offensive zone--10% more than Ovechkin, who has 44 goals. But you're not looking at trading Ovechkin. Just Oshie, who got injured early in this season and is still getting his game back together, after his only thirty goal season, last year. He's a consistent threat for 20ish, and has great hand eye coordination for rebounds, deflections, and stickhandling through the net, though, so trading him plus a bunch of picks and prospects is hard. But Tarasenko might be worth it?

Svechnikov's WJC highlights show a variety of different offensive tools (

That's still a huge overpayment, like, I think you could get him twice for that, but unlike other trade proposals for high picks in this year's draft, the player in question looks like he could play in the NHL, skillwise, and will just need to keep building speed and strength to really contribute. That's much more of what a prospect's highlight reel should look like than what I see on YouTube for Zadina or Hughes, whom Caps fans are trading for, today.
