I believe (could be wrong) that it's less about the "stepping up part" and more the puck retrieval part that is important when looking at the LD vs RD in GB's system. As it pertains to TC anyway. We want EK and TC to have the puck, the RD in this system gets the puck. It's worth trying because if it works we'd potentially have one of our two studs on the ice basically all game. Ceci could be moved for an asset or we ride all three as a position of strength for a year or two while TC eats "baby food" and improves the PP a bit.
That is not walse, but both role are very important. Chabot is a very good puck mover nobody will say otherwise. But ''the system'' argument is overblown in a sense that ''the system'' isn't perfect every back check. It is impossible because hockey is a quick game and you transition from offence to defence in a matter of seconds and you don't have the time to get to the same place every play. It is not football or baseball where every play is separate 1 by 1. Or basket that when the pointguard get the ball he wait for his player to get to place because the opponent cannot stole the puck easily without taking a fault.
Every offensive play you make, you are at a certain place on the ice and you have to know how to maximise your time to get on D at the nearest position that is ask, but then there is also 4 other guys who have to think the same way depending of were others are. It is a very complicated sports when you think about it.
And depending on the offensive time you just had, the puck will go to a certain place and an opponent will get the puck and depending of where his teammate are he will move the puck a certain way to the right side, left side or center.
The point i'm trying to make, and it is going way too long i Know
, is that saying : Oh the LD are asked to broke the play in the neutral zone so they dump the puck and the RD get it back, that's the system GB want them to play is almost kinda bullcrap when it come to deciding where player should be. In an ideal game, all opponent's rush would came from that left side but in reality, the puck enter from left, to center, to right almost equally.
So the LD and RD have to be good at puck retrieval, protecting puck, braking out the puck out of the zone, stepping up when needed. The RD are trying to lock the opponent just as much as the LD.
Last year:
LD-RD
Methot-Karlsson
Phaneuf-Ceci
Boro-Wideman
LD all have attribute about hitting hard. RD all have the attribute of moving the puck well ( maybe not Ceci, but we thought so at the beginning of the year, granted he can skate with it, at least )
GB's system was done for the player he had on D, and if his best puck mover would be LD, that system would be reverse.
All in all, Chabot will play LD at some point, and i understand why he might try him at RD, but it isn't optimal right now.
Sorry for the long essay, but it had the be said, at least that's my opinion.
