MJ....the expansion of the use of the 3 pointer is what allowed the Bulls to dominate the league without a big man. Take away the Bulls run and from dawn of the modern NBA...the merger...........until end of the Shaq/kobe reign...your dominant teams and champs had all star big men....4s or 5s.
Wrong. Pistons didn't have a dominant big man. That 1989 championship team was led on offense by three guards who combined for 65 points/game in the Finals, they didn't have a single big average double figures even though they were playing a Lakers team that was starting A.C. Green (1 block the whole series) and 41yo Kareem (3 blocks the whole series). They didn't have a dominant big in 1990 either.
If you want to take away the Bulls run, then you have to give titles to the 1991 Lakers and the 1992 Blazers, both of whom were without dominant big men. Lakers were starting A.C. Green and Vlade, Blazers were starting Buck Williams and Kevin Duckworth. And the "big man" on the 1993 Suns was a 6'5" Charles Barkley who spent plenty of time on the perimeter.
That's five straight years from 1989 to 1993 without a single dominant big over 6'6" being necessary to win a title even if you leave the Bulls out of the picture. And counting the 1987 and 1988 Lakers with a 40yo Kareem is borderline too, he certainly wasn't "dominant" in their wins. Even the Jazz of the 1990s, Karl Malone wouldn't be any more of a problem for Draymond than he already was for all of the 4's who tried to guard him in his own era. Same goes for Shawn Kemp, or Kevin McHale. Those are all great players, but there still traditional 4's who are 6'10" or shorter and Draymond has tended to guard such players as well as anyone.
Plenty of teams right after the merger that you could say the same thing about. Sonics, Bullets, that first Boston ring before McHale was ready.
Not to mention that for most of NBA history, 7-foot tall Kevin Durant would have been considered a dominant "big man" anyway. Please don't tell me that 6'11" 230lb Jack Sikma, 6'10" 210lb Kevin McHale, 7'0" 240lb Dirk, or 6'11" 235lb Bosh are "dominant bigs" and KD ain't.
