Bridgeport is signing some players, many are not New York Islander players or drafted prospects. One-way NHL contracts (full salary) or two way NHL contracts (one salary in NHL/one in minors) are NHL contracts. Bridgeport/Worcester only signings are not NHL signings, and would require a New York Islanders contract to become an NHL player. Players 25/younger are listed on the prospect site here who have New York contracts. AHL-ECHL only players can sign with an NHL team at any time.
