Okay, so- obviously you can't intentionally put your mallet under someone else's wheel and take them down. My understanding is also that you can't carelessly or recklessly let your mallet down someone- NAH rules say something like 'regardless of intent'. How far does this go? Like, I'm going for the ball, mallet winds up near your wheel you go down. I tap out? I'm sitting in net minding my own business, you ride your wheel onto my mallet and go down- I tap out?
Is there any line to be drawn / argument to be made? Or is it a simple, absolute liability, no exceptions kind of rule: if my mallet is under your wheel and you go down, i have to tap out?
Yes. If opposing player dabs/falls because your mallet went under their wheel, you tap out. Good incentive to keep your mallet in control. I've even seen the polite move of waiting until the other player taps.
