The average age of the team was somewhere around 33
Much older than the average age of todays dream team, Where the average is in the 20s.
Skillset vs skillset, the 92 team are better. No, the game wasn't as sped up as today, but thanks to Jordan and others, today's game is fast paced. But, what happens is that the players, don't take the time to set up, think about the play---they just launch. You see too many blown plays. Bird knew the floor like the back of his hand, Magic, would know that today's players are too impatient, wanting to hurry up, playing into his hands---hurry up means "makes mistakes".
Jordan, well that's Jordan. They would control the tempo of the game, make it more defense than run and gun, thus it would be more grinding it out.
The 2012 team has athleticism---but that is moot if you are impatient, and bullheaded.
