The Leafs are going to burn their future to go "all in".....just to lose to Tampa in the 2nd round.
Their cup window is literally 1 season now. They are going to be in cap jail (40M to 4 forwards), an above average defense (Reilly, Muzzin, Zaitsev) and going to lose a key piece at the expansion draft
As good as their luck has been (hitting a home run with Marner, winning the lotto for Matthews, getting Babcock/Tavares to sign there), it's been clear since day 1 that their defense isn't good enough. Adding Muzzin moves them from average to above average....at the cost of their best prospect and a 1st, and 4.5M in cap space next year.
