Undecided on Chambers atm. I believe drugs cheats should be banned for life, and after the things Chambers said after the ban you couldn't blame the BOA for completely washing their hands of him. However, he's sort of won me over a bit. From all accounts, he genuinely gave Rugby League a proper go, despite having approximately 0% chance of nailing down the technical aspects of the game in a month, and combined with how hard he's tried to have his ban overturned, it gives the impression that this is a guy who actually cares about sport.
Either way, I sincerely doubt he'll run under 10 again, so it doesn't really matter.
