I don't really want to get too deep into this, but just for the record, Wallers comments can't be taken as entirely supportive.
"It's such a sad situation," Waller said, reflecting on the circumstances surrounding Weir's disqualification.
"He had an addiction to winning races, but he didn't need to do what he did – and one day he needs to come out and explain that, which I hope he does.
"Look, there probably isn't anybody in racing who doesn't know things like that were going on and had been going on.
"He took it too far, he was obsessed with winning and with the pressure of results.
"I just hope when he talks that he is understood. People who don't really understand racing in the community will probably never understand, but then if you come out and support him, it's like a black mark.
"One thing is that you can see by the people who are supporting him, the respect he has in the industry and what a genius he was, sure – it was a big mistake."
Before Weir's suspension, he and Waller were close rivals for the national trainer's premiership. The last time they were in competition, in 2017-18, Weir won with 489.5 winners, with Waller second on 337.5 but leading the metropolitan tally 252.5 to 207.
Weir never completed the following season but still had 265 winners to February when his disqualification started. Waller – who rated Weir "my biggest threat as a horse trainer" – finished the season at the end of July with 339 in total.
"He's a genius horseman. I had the utmost respect for him and thought ‘how good is this guy,' and I wanted to know what made him work," Waller said.
Waller has up to eight to 10 horses – including 2023 Melbourne Cup runner-up Soulcombe – in pre-training with Weir and he was glowing in his description of how his horses came back to him.
"It's quite phenomenal what he does. I'll keep sending horses there (to Weir at Trevenson), I wish I could do more, he's a genius."
