They have clearly set a standard for the HoF, to recognise great players who achieved some big accolades with our club. I see flaws with the induction of M Rogers, Stevens and Kimmorley, but there's no denying they did great things in their careers. So that's the standard set.
Clearly the Immortals concept has been set aside as the tier to recognise genuine greatness, and naturally I would expect the only new inductee to reach that milestone will be Gal. In time, I expect Wade and Fifita would reach that level too, but I guess the club is working to a timeline and don't want to shoot their whole load everywhere too quickly.
