To be fair he might just wait till january and see how all the boys interact, or who they gravitate towards..
but my suspicion is Gutho is on the field 80mins per game.. already talking and organising, has been doing it for years, good with the refs.. is his for 3yrs.. just seems like a natural fit... highest paid player at the club also.
Cook could ofcourse do it, great guy.. Sua maybe, im not sure if he actually wants to do it though, or its more just that he was the forward leader in a pack otherwise devoid of leaders (bar maybe Jack)... I think he can lead with action anyway.
