I'm of the view that David has run his race and needs to be jettisoned to the twos, permanently.
But if people actually seriously care that he'd dare wink before having that shot last night, then they need to find better things to get annoyed about.
I saw a few people tweet about it. Amazing. It’s either an umpire telling him the siren has gone, a teammate telling him relax and give it his best etc, or an opponent telling him he’s no chance.
In any case, a nod and wink is a perfectly reasonable response.
