We could see a very different Leafs team than in recent memory. I can't ever remember a time where the team put this much focus on playing defense from day one. The wingers aren't going to be collapsing in their own end. Dmen aren't going to be pinching at the blue line. They are being told to not expect a forward to cover for them. They are really stripping it down and playing a more conservative style of hockey. That over aggressive cheating has always killed this team, and led to odd man situations, easy zone enteries, and terrible zone exits. If this team can't play a simple, conservative game that would be pretty pathetic. If they can there is no way they get outshot and out possessed like they have the last couple of years.
Not to mention half of the team is different from last year. Santorelli, Booth, Komarov, Winnik, Kontiola, Frattin, Robidas, Polak. 8 of the 18 regular players are completely different players. Out are Kuleman, Raymond, McClement, Bodie, Orr, McLaren, Gunnar and Ranger, and Bolland who barely played. Other than Kuly and Gunnar all those guys have major flaws in their games. At least half of them aren't even NHLers. They have been replaced by solid hockey players. Some of which, like Santorelli, Winnik, Robidas and potentially Kontiola are actually pretty good players.
Its a positive that they are spreading money out over the 3rd and 4th lines instead of paying big money to a third line. That is the right thing to do, not the wrong thing to do. They'll have 4 lines this year, and the didn't even have 3 for most of last season thanks to injuries. That alone will help prevent the top players from tiring down the stretch. You just don't need to rely on them as much when you have depth. Especially when there are injuries. And even when there are injuries they have young, talented players with top 6/4 upside, on the doorstep waiting, and probably ready, for their chance, such as Leivo, Nylander, Percy, and Granberg.
Lastly, as every year with this team, if some of the young guys, namely JVR, Kadri, Gardiner, Rielly, can take a jump to another level the Leafs are laughing. I think this could be Kadri and Gardiner's years. They are both 24 which is around where a players offensive peak typically begins, and the same age Kessel broke out.
Who knows if the changes will lead to different results. But they should lead to a different team.
