Tennis should have no room for Kyrgios and his like. Spitting at an umpire? Officials should refuse to officiate at this clown's matches. The bloke is no McEnroe (and maybe it shouldn't matter whether he is or not). His behaviour is unacceptable.

It's surprising that a player who has never won a major and never ranked higher than 13 should be so financially secure that fining him (this last one being to the tune of $160,000) is not working as any form of deterrent.

Everybody's waiting for the administration to throw him out (he is just an abhorrent brand for their sport) and can't understand why this has not already happened. The administration at the moment just appears gutless.

And now, back to the bunker. St George v. Cronulla. The score was 12 all with only minutes remaining. A kick bounced awkwardly towards Wade Graham. It touched his arm.

The replay showed it clearly. The bunker, with what you'd have to assume is superior viewing technology, decided that it hadn't. Graham himself told us after the match that the ball grazed his arm.

Whether the ball was propelled forward from the touch is another question, but you do have to ask: Would we be better off having the bunker referees sitting in the commentary box?

The commentary team are demonstrably getting these things right much more often than the officials.

The situation with the cricket is another weird one. Marnus Labuschagne - our first ever 'concussion replacement' - was 'caught' at square leg by English captain Joe Root.

Replays showed that the ball had bounced prior to Root getting his mitts on it, but the 'third umpire' didn't pick this up (another argument for sitting these blokes in the commentary box) and so Labuschagne headed off.

It makes me question the utility of the third umpire. And, also, it's a little odd that the deployment of the Decision Review System (DRS) is now being discussed by players in tactical terms.

The DRS is now a strategic aspect of the game? Call me old-fashioned but I find that cricketers worrying about 'continued poor use of the Decision Review System' (quoting Justin Langer), and the need to rectify this usage, to be a strange development in our noble sport.

On the topic of the noble sport - this week saw the first ever ejection of a member of the prestigious MCC from Lords for misconduct. The first time ever!

He was jeering at Steve Smith. Keeping in mind that prospective members must sit on an 18 year waiting list to join the MCC: this was a not an insignificant turfing. Maybe the guys running security at Lords should be sub-contracted out between Test-matches to the tennis to sort out Krygios.

And further on the noble sport - did Root really believe he'd caught the ball?

It does strain credibility quite a bit. Labuschagne certainly didn't think so, but the 'third umpire' somehow decided that he had.

It's interesting to ponder our varying requirements for sportsmanship in different sports.

In cricket we fully expect that had Root known he'd not caught the ball then he should let everybody know that the batsman is not out.

It's a required code of behaviour seen as intrinsic to cricket, the abandonment of which is intensely frowned upon, which is the reason the Australian sandpaper trio are still copping so much grief from the likes of our Lords ejectee. (When you bravely head back to the crease having just been concussed by a vicious bouncer and they're still booing you? You've definitely upset somebody)

Football has no such requirement. It's all about whatever you can get away with. Imagine if Wade Graham had told the ref 'I touched that mate.'? We would've laughed at him!

English quick, Jofra Archer hails from the West Indies and his attacking short bowling brought back memories of the great West Indian pacemen of yesteryear.

I do have to ask though: Is it just me, or were we better at getting our heads out of the way in the days before helmets?
