Well yeah, but it wasn't just gifted to them day dot, been in the competition for over 66 years, only after their first 24 years did they make a GF then win a comp year after, then the 2nd 12 years after that, then nothing until now back2back, all with no concessions,
All teams have had to go thru any of that, (except the merger teams, wests, dragons, eagles, but they weren't start up expansions...)
Your logic that the NRL team needs to win a GF or make finals 1st year to be relevant is useless, they just need to not be perennial wooden spooners over the next 3-5years, which history showed that most expansions were either 2nd last or last in this comp...
..so nothing is stopping Newcastle Knights or Auckland Warriors from being a similar set up as Penrith, most teams are trying to copy the format of the acedemy style setups, that the panthers copyied from the bronx, any club can invest in junior development and do what the Panthers have done, they are just too impatient to stick at it for 5-10 years, like Penrith did..
