“It’s about getting the best possible performance out of that human. “It doesn’t matter if it’s sport, business, whatever. I can do it with anyone. I can get anyone to win.

At one stage Stubbs stood on a chair and declared Souths would be the 2014 National Rugby League champions

Stubbs says it’s all-too common for people to get accustomed to the praise that comes their way for attaining success, leading them to slip-up mentally and relinquish that one per cent that had given them an edge.

Stubbs had enjoyed success with people from a whole variety of pursuits – from professional surfers to MMA fighters, account managers, go-kart drivers and company chief executives – when he reached out to South Sydney coach Michael Maguire in January 2014.

Stubbs is a huge supporter of the Rabbitohs, as the club is known, and convinced Maguire to come on board. At one stage in their initial meeting Stubbs stood on a chair in the coach’s office and declared Souths would be the 2014 National Rugby League champions.

The Rabbitohs are the most successful side in the domestic competition, with 21 top-tier premierships, but in 2014 they were experiencing a four-decade title drought.

That is, until Stubbs came along.
