It's easy to see why Benji Marshall did not succeed in rugby.
Blame has been piled on to the Blues coaching and management for their handling of his transition, but did Marshall help himself? Did he explore every option available to learn the game? Did he look closely at himself?
When his signing by the Blues was announced, there were the usual proclamations from Marshall about wanting a new challenge, fulfilling schoolboy ambitions and testing himself against the best.
But how was he to achieve this by watching a video screen, trying to memorise game plans and structures, combined with torturous pre-season training.
Time on the paddock was the best way to learn the idiosyncrasies of rugby, a dynamic sport with too many subtleties to appreciate from a television screen. But being at the coal face did not appear to be an option that Marshall or his management were keen on.
