I was under the impression that only games played for South Freo, East Freo etc prior to Fremantle entering the AFL counted. In Brad's case, he wouldn't have played many games (if any) for South Freo before Fremantle entered the AFL.
That may well be true. All I can find is this:
Until October 31, 2015, Fremantle may include any player whose father made 150 WAFL appearances for East Fremantle, South Fremantle, Perth or Swan Districts.
From wikipedia, also found that on the AFL website (but from 2008).
