Unlike most of the leaders of the dynasties on this list, Michael Jordan did it the hard way. He was by himself until Doug Collins drafted Scottie Pippen in 1987 (via Seattle). Jordan and Pippen would play each other one-on-one daily in order to make each other better, and obviously it worked. Once Phil, M.J., and Pip conquered the Bad Boy Pistons in the early 1990s, the Bulls could not be beaten. Jordan and his crew destroyed the hopes of fanbases across the country and crushed championship dreams of some of the game's greatest players from Ewing to Barkley to Malone and Stockton.

Chicago ran off three straight titles between 1991 and 1993, and another three straight between 1996 and 1998, with Jordan taking his infamous baseball hiatus in the intervening years. The second title run was aided by Croatian star Toni Kukoc and former Bulls foe Dennis Rodman, who were both brought in to help supplement the standout efforts of the Jordan-Pippen core. Chicago went 72-10 in 1996, an NBA regular season record and arguably the greatest single season performance of all time.

If Jordan didn't retire after the '93 season and Jerry Krause didn't blow the team up after the '98 championship, the Bulls could have rivaled the next team on this list.
