 His list of players includes Graham Eadie, Ken Irvine, Terry Randall, Mal Reilly, John O'Neill, Ray Branighan, Max Krilich, Phil Lowe, Paul Vautin, Les Boyd, Kerry Boustead, and possibly his greatest signing, Australian Rugby League Immortal Bob Fulton.As told by people such as Paul "Fatty" Vautin, Arko's negotiating skills often led a player to sign or re-sign with Manly for less money than they were being offered by other clubs.In his biography "The Strife and times of Paul Vautin", Fatty told how in the early 1980s Parramatta Eels coach Jack Gibson offered him a substantial amount of money to join the Eels.
