Andrew Johns' cause was again trumpeted by his brother Matthew in his News Corp column on Friday.

The former NSW five-eighth pointed to his brother's "passion and tactical nous" as reasons why he had to have full control over the Blues' coaching staff.

"When Andrew played football, he was part-coach as well. He came up with plays, sequences and the style of football the team would play. That style had great success against Queensland," said Triple M Grill Team's Matty Johns, on www.dailytelegraph.com.au.

"I believe he could (develop a game to beat QLD), and I'd love to see him have a crack.

"One vitally important thing is, it must be Joey's team."

Andrew Johns told AAP last month he wouldn't take on the full-time role given the emotional toll it would take on him, however he has since indicated that could change.

NSW City Origin coach Brad Fittler is considered the likely front-runner for the role, having also led the under-18s and under-16s squads this year.

The most-capped Blue in history, he was one of the leading contenders for the position when Daley was appointed in late-2012, and his involvement with NSW Rugby League has only increased since then.

Former under-20s coach Dean Pay could also be a contender as could Country Origin coach Craig Fitzgibbon and current Blues assistant and ex-Gold Coast mentor John Cartwright.

Pay is an assistant at Canberra, and has 12 Origin matches of experience to call upon as a player. Meanwhile Fitzgibbon is an assistant at the Sydney Roosters, alongside Johns and Blues captain Boyd Cordner.

Former Manly mentor Geoff Toovey could also be considered an outside chance, given his reputation as one of the Blues' toughest players and his four-year stint at the Sea Eagles.

NSW under-20s coach Danny Buderus and Cronulla mentor Shane Flanagan have both already ruled out their interest, keen to keep their current roles.
