The goal on defense in both rugby and american football is to inflict as much harm as possible on the person with possession of the ball. I'd say it qualifies.
On point two, any evidence to support the fights being rigged? Because after watching Maurico Rua's arm get snapped like a twig, or Tim Sylvia have his neck broken, or multiple fighters get turned into burger, I'd be willing to doubt it very much, at least at the level of StrikeForce or the UFC.
Yes, in that case it does qualify.
As for rigging, multiple fighters have came out of the "sport" and told there were riging. any reasoanble evidence woudl of course result in fines, duh. Im not saying all fights are rigged, but there are plenty, like all sports. And it could be i was thinking of WWE during OP thiknig it was more rigged as those like to be actors and not rights.
