As has been said, learn from your lessons. Get people to talk about why they were shot out, and how they can counter that next game on that field. Everyone does it. A loss is no one players fault. Its everyone's fault. Do it in a huddle as well just off the field straight after the game. Then do a 'team' or whatever it is you do before a game start.
Make sure your a unit on and off the field. Walk to the field together, walk from the field together, as smally says, dick around, make it fun.
