I'd go with this. People aren't THAT stupid. THey'll pull up the score panel at the end of the match and see:
[Boxer1] = OMG KILLS - BBQ DMG
[Boxer2] = OMG KILLS - BBQ DMG
[Boxer3] = OMG KILLS - BBQ DMG
[Boxer4] = OMG KILLS - BBQ DMG
[Boxer5] = OMG KILLS - BBQ DMG
...
[Whiner] = 2 assists; no caps; 8200 DMG
It will be obvious who was slacking.
