1946-47 Brooklyn Gothams (ABL)
1946-47 Allentown Rockets (EPBL)
He is also referred to as Macklin and Mackin.
Slowly piecing this one together. There was a player mentioned as George Mackin or Makin who joined Allentown of the Eastern League in February of 1947. Connie Toombs was on the Allentown club as well as the Brooklyn Gotham that year, and it is possible the he got Makin a shot with Allentown. It is mentioned in a newspaper article that the Makin who joined Allentown was from Manhattan, so I am thinking it is the same guy. So is this player really named George Mackin? There was a Danny Mackin who played basketball at Muhlenberg College in 1946-47. Could be relative.
