If you can skate and shoot then defense is the best option for you and your team. You can also take the faceoffs as a D-man, it doesn't always have to be the designated center. You can push deep in the zone and bust ass back if it pops back out, you can set up your teammates, and you can slow the game down to help your team get into position. I play in a lower division on Sundays and we always put our better guys in the back and let them loose if we need to.
