@mattyb both teams would need to be humanoid robots for the purpose of this question, LOL. Yeah, human vs robot would probably turn bloody..
@mattyb but i do wonder about humans vs robots in a less physical sport like european football (soccer)..
/Bayesian/will-a-televised-football-soccer-ma  lol
@Bayesian i bet no there too.
- i dont think humanoid robots (with that range of functionality) will come that quickly. if it does, i expect them to be very expensive, and fairly flimsy. in either of those scenarios, you wouldn’t use them for sport, at least not without a huge upside (which maybe you’d get; the saudis do dumb shit with their money) 
- assuming we get the robots, what’s to stop the machines from using their superhumanness? the robots would need to be so well calibrated to not blow out/get blown out by the humans. 
- imagine kicking a robot shin. ouch. idk if top players would go for this.
