"When you allow a team like that to get out and get running, get easy scores in transition, the crowd gets into it (and) they gain some confidence."
While Randle ran riot in the South Australian capital, opposing point guard David Stockton underwhelmed with five fouls and just five points.
Henare declined to single out the US import for criticism but admitted he racked up too many fouls.

"Could David have played better and had more of an impact? Sure, but he got in foul trouble and got on the back foot."

"It seems you lose a game or two and end up at the bottom, win a game or two and you're up in the top four," Henare said.
"We can't get too focused on where we are, it's a waste of time."
