I believe this to be true. After seeing comments made by Hodge late in his career that he wanted to drop 1kg per year in his twilight and also AR comments regarding Buddy. I think he's an advocate of shedding a few kgs for players longevity. Cripps probably tried it and said nah not for me I wanna go back to going altered beast mode.Oh bollocks. Cripps does not have the authority or knowledge of sports science to make these calls.
The club (driven by Russell) would have told him this was the best move for him
