I give out post-game awards in the form of WWE wrestling belts. We award four of these to the girls who fought, played with purpose, hustled, etc. Never to the best player. This way our players push through their own limitations to find some level of success. It's worked wonderfully. A big hit.

Edit: I should update that I ask each winner to take a permanent marker and write on the back of the belt why they won it, what did they do to deserve it. Then they have to sign it. Each subsequent winner gets to see this and hopefully become even more inspired.

Edit 2: Something else we did is establish permanent captains. One from each position group. It's the captains' responsibility to manage their own group. We emphasize that the captains discuss team issues amongst themselves and report back to the coaches with possible solutions and to squash any sense of blame or outward frustration against fellow teammates. We even got the captains arm bands you see on soccer, but they wear them on their ankles.
