It's gonna be very difficult to get away from a system that pokes at the puck as the skater skates by and a style that encompasses a lot of standing around waiting for passes plus getting rid of the years of dump and change.
I suspect the new system will require putting the body in harms way, actual skating to loose pucks both in the corner and open ice, going through checks instead dumping and changing or dumping and turning back, the ability to execute a stick to stick pass from both the forehand and backhand, being able to catch the same pass forehand and backhand, skating fast down the ice, skating like a hockey player - knees bent, lower center of gravity and feet moving - instead of like a figure skater - standing tall and gliding - shots that hit the net, etc.
That's a lot of undoing that has to be done in short time during training camp.
Coach Peters, if your reading this, or any other canes official, remember, the game is won on the ice, not the gym. You need to skate them twice a day, once in the morning and again early evening. The first is for basics like positioning, passing, stick handling, shooting, etc. The second is for power skating. I suggest doing the power skating one at night as that is when most games are played and bed will give them time to relax the burning muscles. Plus, who wants to spend the day after tossing their cookies a couple times? They can sleep that off also.
