Contact , that's why.I agree with your point BUT if Warner carrying on like a git goes unpunished, why should Rabada be rubbed out? If Warner is rubbed out, Rabada should be as well. You can't have one being punished and the other not. I think they both should be sat out personally because cricket is a gentleman's sport but if one is ok, they both should be ok.
The drop in standards as a result of this is another discussion but I blame it a lot on Kohli and Indian antics to be honest. Definitely lowered standards these days.
Both sides have been gobbing off for sure but contact is another thing.
If that was kohli he bumped he would have been gone.
Warner should have been dealt with along time ago by us so don't get the idea im excusing that knob.
