The on field character of the team seems to have completely faded, the fielding standards are laughable and it corresponds with the bowling plans being laughable too.
I don't see how Hesson can work with a guy like Williamson, Hesson would be a great foil for the likes of Dion Nash, Chris Cairns, McCullum, Crowe - assertive, extroverted people who drive themselves and their team while they're on the field. He's not a great coach for guys like Williamson, Fleming, Taylor, Vettori who are more naturally introverted characters.
Problem is, we've got no one else in the team that could take the captaincy other than Taylor, at which point you look at the deficiencies in the team and fill them with the coaching staff, we need a Darren Lehmann/Steve Rixon style of coach with this side.
