Hate to burst your bubble, but a professional sporting event gettin a 2-3000 crowd average in the states is embarrassing, bush league material.
High school sports in cities like that AVERAGE 5k+ plus, with upwards of 20k coming out for huge rivalries and big games. Texas has had crowds of over 50,000 for high school state championship games.
Minor league baseball gets around 10k averages in large enough cities, as did Arena football before it closed down.
I think that if Rugby League can't average at LEAST 5k the first year its chances of survival in the states are slim to none. With our population, that number is really unremarkable.
Honestly I think that if marketed right the league could get good sized crowds for MLS stadia, which is what they should be using.
I can't see why Boston has a franchise--I don't know what professional-quality venue they'd play at. New York is a key location but unless they finish Red Bull Arena they are going to have a tough time finding a rugby suitable venue as well.
And these sports have been played in America for how long?
I don't care what crowds they get, if it lasts a few seasons it will grow.
The reason I said those crowds is because it's realistic for a new sport, hell Rugby Union has been played out here for near 150 years, yet their ARC couldn't manage a 2k average.
They came out and said some strange numbers before it kicked off and it blew up in their face, why should Rugby League make the same mistake?
You seem to think it needs 10k plus to even survive, why would it when it will not be anywhere near the NRL and SL? The wages for a start will be no where near what the Pro players in these comps get already.
A decent TV contract will take care of most of the wages for a start seeing as it will more or less be a Semi Pro comp.
Add the sponsorships and other things like merchandise sales which Aussies/Kiwis/Poms/French/Americans and others will buy.
Start small and work your way up, it doesn't need to be the biggest thing since sliced bread.
