Last season the Wests Tigers half topped the NRL with most try assists (37) and linebreak assists (37) but countered that with 41 errors _ the most of anyone in the regular season.
Even his new coach at the Tigers, Mick Potter, is trying to develop him into a more consistent player.
"He is on a different stratosphere with some of the things he can do,'' Potter told Sydney's Daily Telegraph this week. "So it's about getting him to work with the team and realise that not all the time they are on the same wavelength.''
Kearney spoke with Marshall this week and said it was a "very tough conversation''.
"Benji is an immensely proud New Zealander and his desire was to continue in the captaincy role,'' Kearney said. "Although this decision has been a difficult one, it has been made in the best interests of the team, and Benji will remain an integral part of the Kiwis going forward.''
Marshall's replacement will be unveiled tomorrow and, while Newcastle's Jeremy Smith is an option, Warriors skipper Simon Mannering is the obvious choice and would welcome the role.
"It would be a massive honour,'' said Mannering, who was vice-captain last year. "I really enjoyed my time playing under Benji the last few years. He's been there for some special victories. I definitely think he can hold his head high moving on from the role and hopefully he still plays his own game and plays well in a Kiwis jersey.''
Captaincy changes in any sport are rare at international level for anything other than than disciplinary reasons. Last year Ross Taylor was deposed as New Zealand cricket and in 2011 Phil Burrows was replaced by Dean Couzins as New Zealand hockey captain.
Marshall first captained the Kiwis in a World Cup match against England in 2008 and was given the job fulltime in 2009 following Nathan Cayless' retirement.
Losing the `C' beside your name doesn't mean you can't still be a leader and Marshall would do well to remember that.
