Pray tell, what would they learn from him that they wouldn't learn from a good coach? Defensive slides, quick hands, anticipation?
It's like going to a Curry camp for a couple of hours and becoming a great shooter, or a Shaq camp and learning how to dunk on people.
And ain't that rich? Sending money home to mum and dad so he's nearly penniless? Shit, you'd better start a go fund me page for him and a lot of NBA players, the struggle is real! I know when Giddey has his camps in Adelaide they have to slip him a couple of sausage rolls for lunch because Warwick didn't give him his allowance that week.
After taxes and agent fees he earns around $4 million, even if he madly spends on these hangers on and a million or two to mum and dad, he's still a millionaire. If anything he probably wouldn't take the money from this camp, it'll go to the other coaches and staff. It's great to see him showing his face at a camp, but it's very unlikely the kids will be shown any great secret into becoming a great defender that isn't already known. But they'll probably get a really cool t-shirt.
