Crocs? Seriously?
USA needs a single top tier comp, which the USARL most resembles, plus a couple of regional second tier comps, eg, a New England RL comp.
Some USARL/AMNRL clubs would then become feeders to a top tier club - eg Connecticut doesn't need both the Wildcats and Warriors in the top tier, nor does Boston need Oneida and 13s to be top tier.
You could have a pretty good second tier comp with reduced travel within New England and improve the depth of the game. New top tier sides would then be developed through a second tier comp while developing junior structures.
FOR EXAMPLE: New England RL would have Oneida FC, NY Raiders, Turnpike Titans and Connecticut Wildcats for example, plus reserve squads of USARL sides in the region if they have enough depth. I'd want as much expansion at this level as possible.
The USARL in New England would then include NY Knights, Boston 13s, New Haven Warriors and Rhode Island Rebellion.
As to Bucks county and Aston having top tier clubs, well thats stupid. The focus needs to be on clubs in major cities (like say Philadelphia and Pitsburgh rather than Bucks County and Aston), with regional feeder and youth comps. The AMNRL should be wound up, and its best elements integrated into appropriate structures with the USARL.
I'd keep Nui in charge of the National team and developing new regions, but with a club run first grade comp.
