It's a really interesting question from a potential perspective, especially. The Hart Foundation were an integral aspect of the top storyline or lines, if you will, of the companies programming at the time. A timeframe, as well, that many consider, myself included, to be the very peak of the professional wrestling business during the Monday night war era. An era that was not only among the very best wrestling has ever seen but arguably the very best of all, period. The Hart Foundation played a crucial role in Steve Austin's ultimate achievement as the pinnacle of the WWF's success of the Attitude era as well as the emergence of DX, another flagship aspect of that success. Not to mention their role in the birth of mega star the Rock, who benefited from working with them on at very least a casual level and of course how much of his success was born from his work with the aforementioned Austin and DX, HHH specifically. So the enormity of their influence on the three top primary pillars of the very bones the Attitude era was built upon is undeniable, alone. None of that even begins to mention their actual literal accomplishments. 5 hall of Fame wrestlers (yes that includes Neidhart even if it is just for his run with bret in the original foundation which were absolutely a hall of Fame tag team in the 80's), 4 of which were bonded by being family, all of which were trained and molded from the same legendary source. Holding every available championship of the time during their modest around 7 months of existence, almost simultaneously not to mention. WWF Champion, Bret Hart, Intercontinental Champion, Owen Hart, European Champion, Davey Boy Smith and World Tag Team Champions, Owen and Bulldog. Admittedly, the one thing lacking is a long list of legendary moments but again they only had a very modest run, in terms of length of their existence as a stable. But the pedigree of the Hart Foundation '97 all things considered is staggering. The horsemen is the only other stable that competes, which themselves are incredibly compromised by their numerous incarnations of members and even in their best form, giving all due credit, were not collectively on the level of the Hart Foundation in terms of collection of individual caliber talents.
