Not sure i agree.
I'm a big fan of de Kock but he loves giving the chat out.
If he gets it back, he has to take it in the chin.
I still think Mills is a chump.
I'm all for some banter out in the middle but I hate send offs as the batsman doesn't have a leg to stand on. When he's out, then you've won the battle, no need to rub it in... I've seen so many bowlers who have been smashed round the park and say nothing and then, boom a wicket, suddenly they're the worlds greatest bowler.
Unless he's been giving you flack all game, then let him have it.
