I hope Suli comes good. I don't know him so maybe there's more than telling him to harden up. If he has friends in the Manly team I hope they can help him out and get him back on track.
Admittedly no one wants to be a nurse-maid for years (unless that's your job), but I hope he wants to get fitter and his team mates want to help (coaches too).
Part of me hoped that someone took him aside and went "Hey, you think this is making your late father proud? Your actions would have him smiling down at you? We just went to NZ and visited sites where 50 people had their lives extinguished and a whole nation has been changed forever. People looked to you for a bright spark in a terrible time and you got to provide it by simply playing a game you love while earning a good living. Time to pay back all those who you owe and maybe grow up."
But also, it may not be that easy, so I hope he gets what he needs.
He's also got a sore calf, so...
