Williams, who won an Investec Super Rugby championship and a World Cup while playing rugby in New Zealand, is about to make his return to rugby league.
Many believe that Williams is a good chance to return to New Zealand in the coming years, with the dual international admitting that trying to force his way back into the All Blacks for the 2015 Rugby World Cup is on his mind, while he said to the Sydney Morning Herald that playing Sevens had a massive appeal.
"To win a gold medal sounds pretty good," he said.
"As a sportsman, if you don't have those sorts of dreams or aspirations then you may as well just stay in bed."
However Sonny Bill did admit that boxing wasn’t his ideal choice of sporting profession, with the experienced Botha giving Sonny Bill a huge fright before the former All Black took the bout on a point’s decision.
"I think I am best at putting on the boots and running out on the field to play rugby union or rugby league," he said.
"If I had lost that fight I would have given it away because it is just not worth it, but I overcame some hurdles and the reaction of all the people close to me was good so we will assess it when the time is right.
"For me, boxing is a challenge. I am not perfect but I am just trying to keep improving and if everyone is saying I have improved then I will just keep plugging away and maybe have another fight (but) at this stage, I have had enough of boxing for now."
