I know that this won't exactly be popular, and no I'm not basing it entirely on his performance in the playoffs, but I really think that trading Zaitsev for a quality left-winger might be something that the Leafs should look into this offseason. I don't think that we'll get as lucky as New Jersey did with Larsson for Hall, but if we can get anything close to that it's something we should at the very least explore. I'm also just not convinced that his value will ever be higher than it is right now.
I will add the one condition being obviously that we need somebody to replace his minutes on the right side for next season if we want to still compete. But since this is an armchair GM thread I'm going to armchair GM.
-Trade Zaitsev for 'mystery top-6 left winger for Matthews'
-Sign Shattenkirk and Brendan Smith
-Clear cap space where necessary, starting with Bozak. While his play has absolutely won me over, I think his value too is at the highest it will ever be
-If we end up losing Martin in the expansion draft or trading him, I'd bring back Boyle for the 4C
-*shudders* bring back Hunwick. If it's a cheap deal, the extra depth can't hurt. I just hope he doesn't get guaranteed minutes again
