Puig
That's what Puig was PAID to do; find talent. Hardly a philanthropic endeavor.
I will answer - nothing.
But he did help many younger riders while racing (US riders come to mind) and fought for the 125cc guys to have paddock rights that they otherwise did not have.
Now as for Aussies that have helped their countrymen I suggest you look on the back of a postage stamp for the answer because the answer is very small.
Gardner - helping family
Doohan - nobody
Magoo - nobody
McCoy - runs a ride school but not tailored at international level
Bayliss - probably the most helpful but again, more localised but has used influence to get a few guys WSBK rides.
Vermuelen - not sure to be honest
Many of these guys do poke their heads in at junior meets from time to time but at the same time, one thing that the vast majority of Aussie sportsmen and sportswomen do is that they do not seek publicity for their assistance so many may well be helping far greater but we just will not know of it
Facts are that in this country we do not have a conveyor belt of racers that we had in the past so the chances to help are greatly reduced plus none of these guys made the money of a Rossi nor have the business connections, thus opportunity to help is greatly restricted anyway.
The Aussies that are 'putting back' if that is the right term are the likes of the Cudlins who run a junior race program (MotoStars) where the likes of Bayliss, Vermuelen, McCoy etc will show their faces from time to time to help the kids (source - know someone very closely involved).
Besides, why should they help (Serious question)?
Once a person retires from work, do they use their money, their skills to help people who replaced them or are they off enjoying retirement?
Puig
Do go on . . .
The whole Stoner family lived in Puig's father's yard for 18 months.
Rossi Single handedly took Morbidelli, a kid with a broken family and no hope of even competing even on national level and developed his career to the point where he got a MotoGP ride. Ditto Bagnaia. And many more to come.
What has Stoner done since retiring? Teach upcoming OZ racers fly fishing?
Rossi single handedly has done and is doing more for the sport than many past and present racers have ever done. I am sorry if this uncomfortable truth offends some.
Also, Rossi didn't really receive much help from Graziano other than in the very early years of his career. His career in the world scene was pretty much driven all by himself and not his dad. That is a sharp contrast to Marquez, who is living the Tennis parent fantasies of dadmom Julia and uncle Emilio (That's not a knock on MM's talent).
ROOKIE MISTAKE
The whole Stoner family lived in Puig's father's yard for 18 months.
He is not required to. He was never one for PR work! He is not a glory hog like 46. Are any of the previous Australian champions running a race academy?
None of them on a Ducati, or on a Honda with non-SNS tires.
You are a child of a lesser god anyway. How many world titles did Valentino have before he turned 25. Marcy Marc had 6.
I know it cannot happen but I wish VR would stay around until Marquez wins the 10th MotoGP title. I would pay a lot to see that.
Garry McCoy runs a race academy for dirt and road riders
Bayliss assists with coaching for some
Cudlins run Motostars
