Boston was a super team by the old standard of the term but Bron and Wade (Wade always gets a pass but he should get just as much heat since he basically gave up once he handed the reins over) issued in a new type of superteam.
None of KG, Pierce, and Allen were considered consensus top 3 to top 5 players. They were all 30 and above as well. Age isn’t even the most important part tho. It’s there status in the NBA. You can be 30 and still be the best player in the NBA. At the time, they were not top 5 caliber players. KG was the only one who was even top 10.
Lebron and Wade were both widely regarded as top 5 players if not top 3 players in the NBA. Bosh was at worst top 15. All in there primes. It’s a clear difference
And you also have to look at the landscape of the NBA at the time. When Bron made his move, Boston had been proven to be beatable. There were no other teams with extreme amounts of talent. The intention was clear. They knew it was unprecedented. That Miami team was made to crush everyone.
Ignoring the age differences for a second, it’s like comparing a super team with KD, Lebron, and Jokic to a Superteam of Bradley Beal, Joel Embiid and Chris Paul
. There’s a clear difference in caliber between the top groups.
Since then it’s been the craziest arms race with the deck stacking getting worse and worse.
So on one hand, yes I agree to an extent that Boston started it. But LeBron, as the budding face of the league, next in line in the GOAT convo, took it too a whole other level when realistically it was not necessary. Dude would’ve beaten Boston within the next 2 years without the drastic leap. Now KD has taken the mantle by 1 upping Bron. And they’ve been in a battle to just keep outdoing each other. Now any other star is forced to play that same game if they reasonably want to compete, which is a damn shame
