The more I think about this proposal the worse it seems.
Assuming there is an even split of central income, it would essentially mean reverting to a sport played by 24 village teams. If there is not an even split of income then the bottom four in SL would all be full time and they'd play the majority of their season against part-timers from the top four clubs in SL2. They'd be almost guaranteed promotion back to SL at the end of each year. What good does that do for anyone? I suppose it would give the pretence that there is P&R.
I'll say it again, we do not have the finances, the players, the spectators, the corporate support or the media coverage to sustain anything more than a 12 team elite competition. And the key word in that sentence is elite. The most likely outcome of this proposal is that the game in this country becomes nothing more than a nursery for the NRL. Or worse, rugby union.
Your right that how this would pan out depends on how the TV money is distributed. But in the absence of an answer to that one has to assume there's no money for a second tier.
I disagree on your analysis "we do not have the finances, the players, the spectators, the corporate support or the media coverage to sustain anything more than a 12 team elite competition".
You should wait whilst
a. Wakefield get Newmarket or not
b. Toulouse get civic money and /or a French TV contract
c. Koukash actually spends some mega money
d. Nahaboo delivers on the promise to fund Fev all it takes.
