To clear things up
Taylor Alley - Central Florida Warriors
Luke Barron - Mitchelton Panthers *Actually from the CT Wildcats and Kristian Freed invited him to play in OZ for the season. So really a USA player, but played the last season in Australia.
Ryan Burroughs - NOVA Eagles
Sam Carson - Norths Devils
Casey Clark - Philadelphia Fight
Abe Cohen - New York Knights
Kristian Freed - Mitchelton Panthers - played for the CT Wildcats in 2013 and WC last time round
Rich Henson - Philadelphia Fight
Danny Howard - Wentworthville Magpies - WC Qualifiers and WC Team last time around
Steve Howard - Wentworthville Magpies - WC Qualifiers and WC Team last time around
Taylor Howden - Mid-West Stockyarders - Mostly Union, from NZ but USA resident since 2008. Has helped RL in the Midwest and the Chicago Stockyarders out him forward.
Andrew Kneisly - Philadelphia Fight
Roman Lowery - Philadelphia Fight
Nick Newlin - Atlanta Rhinos
Mark Offerdahl - London Broncos - CT Wildcat for 2013 and WC team last time around
Jon Purnell - Jacksonville Axemen
Tui Samoa - Young Cherrypickers - American Samoan and I believe WC team last time around.
Mike Timpano - Philadelphia Fight
Matt Walsh - Connecticut Wildcats
Kevin Wiggins - Delaware Black Foxes
So the only guy who has not previously played for the USA National team, OR for the USA Domestic Comp is Sam Carson, who was bought to the attention of the USARL by Steve Johnson. After all checks were made, he is a great young player and seems to want to help develop the game in the USA as a player.
And to answer the question on limits. My personal belief is that in any 17 man roster only 8 should be "non-domestic" players. This limit ensures that there is always a majority of domestics (9) in any named team, and always 5 on the field.
And by domestic, I mean a USA Citizen OR someone who can claim residency (usually 3 years) and has registered and played at least one season in the domestic USA competition. Thus having helped grow the game domestically.
That would seem (a) fair, and (b) ensure there is always ample opportunity for domestic players to aspire to.
Lets be honest, if you cant be competitive with only 5 domestic players on the field, are you really developed enough to progress past teams? With 8 "heritage players" whom we will assume all have at least high level QCUP or NWSCUP (or higher) experience on the paddock, can we not find a place for 5 domestics on the field at any time? If not then more work needs to be done on the domestic development.
