What Penrith have achieved is remarkable and obviously unprecedented in the salary cap era. Trying to say they are better than the Dragon's of the 11 in a row era, the subsequent Rabbits of the late 60s/early 70s, the Eels of the early 80s and then the Dogs of war who basically had 2 test level forward packs is great conversation with no definitive answer given different rules, players being semi professional, and the at times thuggery that was allowed.
