Also, as a defenseman, it is frustrating when the forwards fall back too much. The wingers really need to stay with their pointmen, and the center should fall back to the low slot when the puck gets to the endboards. When all the wingers and center fall back, it's hard to cover as a defensemen because there are to many people to skate around. Also, one we get the puck, it's easier to break out since their defensemen/pointmen will not have as much ice to set up a wall since our wingers are already in their face.
And when we are attacking, don't forget about us on the point! When all three forwards are low in the slot, and there isn't room to maneuver and there is no shot, send it back to one of us. CHances are, we'll have a good shot with a screen since their are so many bodies, or we can play quarterback by slowing the play down, giving you a chance to break from your marker, and passing it to an open man.
Finally, don't forget that you can skate to the sideboards. Basically, every single game we played, as soon as we crossed the blue line into the offensive zone, everyone broke towards that middle and created a bottleneck.
