One thing I'll be looking for this season is a bit more aggression from the D in the offensive zone.
My theory, though it's not my own and I probably stole it from someone without realizing it, is that the change from December 2018 to today on the way the backend plays is because Maurice doesn't totally trust the defencemen he has. That was compounded with the losses of Buff, Trouba and Chiarot. I think now with a top 4 of Morrissey, Schmidt, Dillon and Pionk he will not resort to having the D immediately drop back when they lose possession deeper in the o-zone.
