The goal is to make Super League more attractive to sponsors and TV companies. It is likely that Toulouse are seen as being more capable of this than, for example, Leigh.
Boosting the game in France is secondary to that, I would imagine.
Why is it likely? New market, yes. BUT.
[and this is all hypothesis]
TV- do we risk losing cash from sky (fewer english teams, people aren't going to want to watch Toulouse get smashed for the next few years) whilst not making as much money back from the supposed French TV deal (there's only two teams in France, so why are we paying a load of cash?). Let's not kid oursleves that for the first few years at least this is going to be conisdered like the CL or the HC
Sponsors - ok, so there is a larger geographic footprint. So I suppose a global megacorp might be more interested. But are they going to be interested enough to do all the promotional stuff in two languages? Also, will they really see that much more benefit from having Toulouse AND Cats vs just Cats? On the other hand, are we chasing away smaller british sponsorship? In terms of local sponsors, why would a french company sponsor anyone other than Toulouse or Cats? Does that actually enrich SL as a whole?
I know that the TV negatives at least are potentially short term, but do we have the ability to survive that loss of money in the short term?
