"You see Rona and [Force winger] Chance Peni, they've fitted in quite nicely.
"I don't know much about Chance Peni, I always thought Rona was going to do well.
"He'll need a bit of time but I think he'll be very similar to how Ben Te'o has gone for England.
"He is a big player, he's a good defender, he's got a fair bit of aggression."
Cheika said he'd also been impressed by Rona's centre partner Bill Meakes, Rebels fullback Jack Maddocks, Brumbies halfback Joe Powell and props Alan Alaalatoa and Tyrel Lomax, NSW hooker Tolu Latu and Queensland lock Izack Rodda and backrower Adam Korczyk in the first two rounds of Super Rugby.
