The big risk with both the Tui and Hurrell signings are keeping them both in good shape - both have a history of not looking after their diet, fitness, weight and looking at Tui in the warm up for this Tonga/Aus game, he's looking a tad more chunky than usual - not being in the Wests team at back end of season and a few weeks off looks to have taken it's toll. But he is a super talent, be interesting to see how he plays against Aus.
