For one, even Kobe doesn't think '12 could beat '92 in a series.
“They have (Patrick) Ewing and (David) Robinson and those big guys. It’s tough. If you’re asking me, ‘Can you beat them one game?’ Hell yeah, we can beat them one game. You didn’t ask me if we could beat them in a seven-game series. In one game, we can beat them. No question about it.”
Second, the only real argument I can see in favor of the '12 team is athleticism, and even that's not much of an argument. Lebron is superior to anybody. ever. PGs Paul, Williams are probably more athletic than John Stockton and Magic. But, other than that, I would argue that the '92 team was as athletic or more athletic in the back court. Kobe and MJ are a push. Bird and Durant are a wash (yes I know Bird is a white guy with a mullet and Durant is black, but they play a very similar game). Pippen and Clyde would face eff guys like James Harden and Russell Westbrook. Front court isn't even an argument.
'12 are allegedly bigger, stronger, faster - across the board. let's not forget, we're talking about 20 years ago, not 50. We're not talking about Pete Marovich, John Havlocic and Kevin McHale. The '92 guys were sick.
