No, you're not wrong and there was also the fact that the NRL get a revenue stream - however comparatively small - from NRL Fantasy, where you can pay - I think it's AUD$20.00 for a season - to use Super Coach or whatever it's called (I'll probably use it when I'm 0 from 2 after this weekend!

). It was pointed out, using your Thurston example, that it was bloody annoying when Mr NRL Fantasy Player would sell Thurston because he was apparantly injured so wouldn't play this weekend so that's a waste of - say - $950k salary cap so Mr NRL Fantasy player would sell Thurston and spend $850k to buy
Johnson and then, holy cow, Thurston gets confirmed to play one hour before the Cowboys game and by then, Mr NRL Fantasy Player's at the pub with the boys, can't access his NRL Fantasy team and
Johnson has a naff game and scores 20 while Thurston has a blinder and scores 95 etc etc.
I don't think the 21 system is perfect (for instance, I'm not sure if clubs are barred from moving Player 13 out to 21 and then subsequently claim "well, we
did list him as an outside chance! Look at our website article dated 4PM Friday!") but I suspect it's as close as we're going to get.
