More than 1000 people turned up and most were there to see the potentially dynamic centre pairing of Richard Kahui and Williams, Clarke said.
"Sonny and Kahui got swamped."
Quite what two of the pillars of New Zealand rugby, Colin and Stan Meads, made of it all is hard to say. The Waitete old boys were there to watch and, magnanimous as they might be, it must be a source of amusement to them that a fringe All Black-cum-boxer can generate so much fervour.
The Chiefs are welcoming the attention after a couple of flat years.
"When he wasn't here there was a lot of hype around Sonny and we've been in Hamilton seeing the buildup around his boxing so we're well aware that [the attention] comes with the man," Clarke said.
Clarke made his Super rugby debut for the Crusaders in 2006, had a spell at the Hurricanes and is now part of the furniture in Hamilton, where he will start his fourth season for the province.
He said the change of coaching regime, which has seen Rennie take over as head coach joined by former All Black assistant Wayne Smith, had given him renewed impetus.
"It's a fresh start ... There's a different mentality. We've got to prove ourselves again because we're not so comfortable with the new coaches. We're fighting for spots."
Southland's Robbie Robinson is on at fullback, a move which has seen Tim Nanai-Williams shift to the wing.
