"One thing I have learned in the last two years is you are only as good as the stock you have and I am lucky in that regard," says Richards.
The Shark is a marketer's dream, a big, bold chestnut, able to swoop home from last, looking the living ghost of Super Impose or Bonecrusher.
Chuck in some loud owners wearing crazy hats and a horse who can run his last 600m in close to 32s and it's party time.
Te Akau Shark mowed down some serious Group 1 horses in the hands of Opie Bosson on Saturday and now is hot favourite to do so again in the George Ryder in three weeks and is second equal favourite for the A$4 million Queen Elizabeth on April 11, where he meets Japanese star Danon Premium.
But while The Shark wins money and fans, Probabeel's first Group 1 may end up being worth much more.
Already a two-time Karaka Million winner, she added an Australian Group 1 against magnificent fillies, overcoming a flat spot at the 600m to come from near last.
The 1400m was below her best distance and she might keep stepping up all the way to the 2400m of the Oaks on April 11.
Every Australian Group 1 adds to her enormous broodmare value for Brendan and Jo Lindsay, who are rejuvenating the broodmare band at Cambridge Stud.
They have some serious female horses around them now, with Probabeel the best, and she could become the famed stud's next champion. So what she achieves this autumn and beyond could pay off for years, decades to come.
Like Richards, Probabeel might just be starting her own legacy.
