In response to that first part of your post, the evidence is in his new and improved frame, coupled with what Millward and co have been saying. He has obviously trimmed down and is looking a lot fitter than he has in previous years, that much is obvious. You don't achieve that if you haven't made the decision to improve your effort at training. In relation to what the coaching staff have been saying.. I don't remember one occasion last year when Mary or Millward have said that they've "seen a change in him, the way he trains and goes about his business". If he was a lazy oaf at training then I highly doubt they would have re-signed him for a further two years, regardless of the Thompson situation.
Leilua deserved game time in 2017, it wasn't his fault he didn't get picked. He was in the NSW Cup team of the week 9 times or something ridiculous like that, playing 80 minutes nearly every week. Apparently it was his "education" year, which is questionable, but if it's going to make him a better player then so be it. It obviously reflected a lot about his character if he was prepared to bide his time in reggies to earn that contract extension.
Agreed about Graham, i'd love to see him get into the kids ear and pass on some of that mongrel. I fear for whatever poor halfback that will have to tackle Luch 5 metres out from the line after hitting a short ball from Hunt at speed.
