This is what is going to happen if we are being realistic. Gio can play the right. So sandin can play his strong side and try to play past muzzin. Solid shut down line and if roberston doesnt work out they have room to add at the deadline or earlier.

To quote my favorite Detroit authority, @Deadwingsv2:

Detroit does not now, nor ever, want:
Kerfoot, Holl or Muzzin, regardless of cost.

Just no room for kerfoot in Detroit unless they do something else first. Like player and 2 seasons ago sure but not now.
