If we keep Gio/Lily together, and I think we should, for the other pairings it seems our options are:
Option 1:
Rielly - Brodie
Muzzin - Holl
Option 2:
Rielly - Brodie
Muzzin - Boosh
Option 3:
Rielly - Boosh
Muzzin - Brodie
Personally, I like option 3 best. Any pairing that leaves Muzzin with another bigger, slower, less talented puck handling dman (Holl or Boosh) seems like a bad call. We end up with a pairing that’s just too slow and weak in transition.
IMO, the only sensible partners for Muzzin on the Leafs are Brodie and Lily. While Boosh is a weak-ish partner for Rielly, this option does leave us with 3 strong pairs overall, and I think that’s crucial. IMO it’s more important to have strong D all game long than 1 great pair and 1 weak pair - the weak pair will get lit up.
The other option is splitting up Gio/Lily, but I’d try to avoid that, they’ve been so good together.
