Just finished watching the 3rd episode of the Amazon series focusing on the Boston/Florida series last year.
After the Panthers beat the Bs for the second consecutive year Pasta said (paraphrasing) "They're a nasty team, very tough to play against." Until an opponent says that about the Leafs, they won't win anything.
The Panthers took it to the Bruins and never let up the entire series. The Leafs pounded the Bruins hard in game one (but lost anyway) then let up.
Treliving/Berube have their work cut out for them. They have a bigger, tougher blueline but it's the forwards that need to embrace the mentality: Beat the SH!T out of your opponents, aggravate them, get in their goalie's face, be like a pitbull on the puck, drive to the net like a runaway train. Then come back to bench, take a few deep breaths and go out there and do it again, every shift.
Let's see if there are any signs during the season that they finally understand this or are they still going to try and dangle, shoot from the perimeter and hope that their skill alone wins them games. I'm not optimistic at all, but even halfway to that could open the doors to a mindset change this group desperately needs.
