The Blues want to talk to double rugby-league international Mat Rogers to help Benji Marshall ease into the 15-man code.
While the Blues have plenty of rugby league knowledge to help Marshall with his transition to Super 15 next year, one former league convert to rugby - Blues backline skills coach Grant Doorey - says a chat with Rogers would be useful.
Rogers was the most recent player to make the same code and positional switch as Marshall. At some stage, they would like to chat to him and others who might have had similar experiences.
"He worked close to the ruck and we would like to find out what his biggest challenges were and, if he had a second crack at it, what he would do differently and what worked for him," Doorey said.
"There is not a lot of research out there that you can tap into. But I am sure Benji has got a lot of knowledge and can take confidence from that. He played age-group rugby for New Zealand so that base is still there."
