The Hawks continue to support the growth of rugby league in the United States by selecting fourteen players who have played in the amateur USA Rugby League competition, three of whom have since been signed by professional clubs (Burroughs, Eichner, and Offerdahl). Nine members of the squad (Faraimo, Farley, Freed, both Howard brothers, Marando, Offerdahl, Pettybourne, and Shipway) previously represented the Tomahawks at the 2013 World Cup, and three players have experience in the NRL, all of whom are eligible to represent the US through their American Samoan heritage (Faraimo, Pettybourne, and Vaivai). Samoa, also of American Samoan descent, was a late inclusion to the squad due to an injury to Matt Walsh.
