I'm thinking you do. You know the ENTIRE ball has to have passed the ENTIRE line to be out, yes? So that means the centrepoint of the ball must be at least 11cm outside the line to be considered in, given the diameter is around 22cm? so, logically, that would mean you can have grass between the bottom of the ball and the line, while halfway up the ball is still over the line, wouldn't it?really gus . whats wrong with what i've posted ? sounds like you have a problem with high school geometry
I have absolutely no idea what the relevance of the tennis shot you posted is.
And you are yet to explain what is wrong with the tennis ball example I posted above (and your argument against the soccer example was very weak as well - clutching at straws)
