Going from McCabe to Zellweger or some alternative to that regardless of the picks we'd have would not improve us in the slightest.
McCabe was our #1 last 2 seasons, played a lot of very tough minutes, but he did struggle last year (who didn't?). I'm fine with selling high here and pivoting, but it will be very very hard to find that kind of hard nosed defenseman. If the Leafs want to push for the playoffs, this won't help unless they make some pretty creative maneuvering that is hard to phantom.
