Isn't that just an outcome of our racing being so weak though? Take the WFA this week as an example, you could make an argument for 3 or 4 horses being genuine G1 NZ class , there is also an argument none of them are international class? That top layer of horses is also being reflected across the board in NZ and thats why that stables dominance is so prevalent.
The quality of animal in that stable is so far beyond anything else in the country at the moment that statistically they are going to be successful , barring any significant bad luck. Have a look what they line up at midweek meetings and couple that with the pool of jockeys they have at their disposal and you'd have to be pretty delusional to not see why it all comes together.
As for comments regarding MB ,OTB, Brando & Amamerilinha 57.5k,90k,500k & 300k are significant purchases when you're racing in NZ well at least in my humble origins of the sport. Now take a look at what this quality of animal and jockey they are lining up against in NZ ( I think its getting worse as well) and that gives it a bit of context.
Agree and don't get me wrong I think he is an extremely hard worker and deserves his success but it does need to be put in some context.
