So when the Russians were barred from Rio, Leslie's reaction was sought.
He said nothing. A journalist, Leslie isn't short of an opinion. But he also knows how to give a "no comment" quote by saying something, when you're actually saying very little.
Leslie's response was along the lines of "I'm not focusing on the other swimmers - I am focused on my training and my times."
But it must have been a psychological boost for the Whangarei swimmer.
Unusually for Leslie, a week out from his specialist event he predicted he would break the world record, which suggests that he had been hitting some quick times in training, and was feeling good physically and mentally.
His prediction was correct - and he didn't just break it, he smashed it by two seconds.
It was a pleasure watching a Northlander do well on the international stage, and seeing Leslie's gold-medal grin beaming across the planet into our homes and offices. And the pride of the Team Cameron support crew up in the stand.
Well done, again, Cam.
