As usual, I'm somewhat late in joining the discussion. Just want to throw a few thoughts out concerning this issue of problems with our D , and the issue of player size.
Suggest that the fundamental issue is still systems related - which has led to confusion as to basic responsibilities handling a rush attack, and particularly, confusion in setting-up against a sustained attack below our blueline,( when teams are cycling high/low or low behind our net and in the corners). While our D would absolutely benefit from a change to a more standard zone type defence, the chaos also starts because our forwards fill their responsibilities so poorly - either in simple back pressure checking, or, positionally within our end . In my mind, all of this can be sorted out with a fundamental change in coaching philosophy - but Huddy has to go and as soon as possible.
I suggest that we err in talking about needing bigger D who will "clear the netfront" - this is an archaic approach which worked only in the distant past when the league allowed all kinds of interference , clutch and grab, and physical abuse at netfront by way of cross-checking and stickwork. Our D do not have to necessarily be bigger/meaner, BUT, they do seem to be surprisingly poor at executing basic assignments. If you can't "clear the netfront", you can still "box out the netfront" and most importantly, you can still"tie up the guy's stick" so he can't make a play. You can still be"in the proper position" to avoid creating another level of screen for shots from the point, and you can still be "on the right side of the player/puck" when along the boards. I have to believe that our guys can do much better at all these things IF they can get organized to the point where the pressure/chaos is reduced to a manageable level.
Just my 2 cents.
