It would certainly change how the cherry pickers on our team play, Nylander would hate his system, Samsonov and Murray would instantly become legit 1A & 1B goalies. Trots coaches the game right, no cheaters, no passengers. Marner would be instant Selkie candidate, year in year out.
For me, this team plays an immature system, keep the puck at all cost and out individual skill the other team, which works well in the regular season when you play teams with lesser individual talent. IMO they have out grown their current system and coach.
In the playoffs every team has "some" high end talent, everyone, even the crappy Habs had Price at the top of his game + a coach in Richardson who simply out coached our system. There is a reason why we are out in the 1st round every year, the immature system we play is not a playoff system. The kind of positional accountability that you need to win a cup will never be in a Keefe coached team, its simply NOT a playoff system.
Then you get the "Yeah buts" Keefe is 123W - 53L -19OL (.674 winning %). He is the Leafs regular season most winning % coach of all time, that must mean something right? For Leaf coaches who have coached as many or more playoff games than Keefe, Keefe has the 7th worst winning % (out of 10 coaches), (.421%). He;s .350 points worse in the playoffs, does that stat only scream out to me? That means something, that's probably the most important Keefe stat you need to look at.
Elite skill in the regular season hides a lot of systematic warts, warts that you don't see in the regular season, that get exposed in the playoffs. Hire Trotz, end this charade of shinny hockey.
