First point, is yes of course the records came across from the NSWRL. I'm not denying the current system, I'm arguing for it to change.
The newly formed ARL (in 1995), which was formed to supersede both first grade comps (NSWRL and QRL) so we only had one first grade comp in Australia, should be acknowledging the history of both comps. It is a national body (and people forget this part) that is separate from the NSWRL, if it was just a name change, the NSWRL would have ceased to exist.
Now, this has never been a problem before because no QRL brands have been admitted to the NRL until the Dolphins. Now that they have been admitted though, there is zero reason to not acknowledge their first grade premierships OR have everyone start again from 1995 onwards.
I know I'm not going to convince any NSWmen on here of this because your clubs' records are acknowledged by the national body, but those outside of NSW will get what I'm saying.
Let's remember that many Kangaroos were picked straight out of the BRL to play for their country before the 90's and the NRL was more than happy to lean on the Dolphins' history to drum up interest in their Queensland expansion efforts. So they should be consistent and impartial and acknowledge it completely, not just when it suits.
