He could. He is just playing in a shite system.
I call BS based on the only evidence we have which is
Roger Tuivasa-Sheck playing for the Warriors, Roosters and the Kiwis. The latter two are both great teams and yet
Roger Tuivasa-Sheck has only ever played wing or fullback and can't manage to be a support runner in any team..
Whereas Turbo has slot in at wing, fullback and centre with aplomb for Manly, NSW and the Kangaroos and shown the impetus to support his team mates and force a chance into an opportunity..
As good and inspiring as
Roger Tuivasa-Sheck, IMO he lacks the ability to make the players around him better by
playing to their strengths instead of his own..
