"I didn't hear back so I took that as a no," Kirwan said. "From what I've heard, he's a talented player. A bit like Sonny Bill, it might take him a while to get used to things but it would be worth the wait."
It is understood Chiefs coach Dave Rennie chased Folau until September, when it became obvious the player wanted to stay in Australia. Former league star Williams was a hit for the Chiefs last season before deciding to move back to the NRL.
Folau was a superb finisher at centre or on the wing with the Melbourne Storm and Brisbane Broncos before his switch to the AFL.
The Australian-born player of Tongan descent made his NRL debut for the Storm at the age of just 17, scoring 36 tries in 52 games before moving to the Broncos where he scored an incredible 37 tries in 38 games. At 18 years and 194 days he was the youngest player to make his debut for Australia.
He would have given Kirwan's young team incredible X-factor and crowd-pulling ability.
Folau's willingness to try something new was also attractive to Kirwan. "He's courageous - it was a big move to go to the AFL," he said.
Kirwan's outside back options include Rene Ranger, George Moala, Waisake Naholo and Frank Halai. The latter pair, both sevens experts, will be making their Super rugby debuts. Powerful runner Charles Piutau, who is also a relative novice, is likely to concentrate on fullback.
The Blues coach was philosophical about missing out on Folau, saying he had plenty of faith in his squad, but he confirmed he also tried to attract 100-test former All Black fullback Mils Muliaina, who moved to Japanese rugby after the World Cup, to the Blues. "He has decided his future lies over there. His club [NTT Docomo] have offered him a coaching position, so he will make that transition there." APNZ
