It is not taking advantage of the rules as you say, it’s taking advantage of a bad call from the ref. You have five minutes to recover from the foul. Not five minutes to recover your gas tank. The kick clearly didn’t affect him, he just took the opportunity to take a breather. I thought it was lame, definitely outside the spirit of the rules but the ref gave him the break so I blame the ref. I don’t think anyone’s saying what he did was a foul, but it’s definitely not within the rules like you say. It’s just that it’s the refs job to enforce the rules, and if a ref gives a fighter a good break you can’t blame the fighter for taking it.
