RANKED: The 25 Greatest Teams in NBA History

21. 2007-08 Boston Celtics

The 2007-08 Boston Celtics featured the first modern day big three with Paul Pierce, Ray Allen, and Kevin Garnett. The Celtics went from a 24-58 record the previous season, to an astounding 66-16 record. With the acquisitions of Allen and Garnett, they became instant title contenders, and Doc Rivers turned them into a force on the defensive end. This team was pushed to seven games in their first two playoff series, but then they seemed to hit their stride, beating the powerful Pistons and Lakers in six games each.

A 21-year old Rajon Rondo seemed to grow a lot throughout the season, and playing alongside all-star veterans, he was able to turn into a point guard that could anchor the team. This Celtics squad was impressive on both ends of the floor, and they absolutely cemented their place in history amongst the best teams of all-time.

20. 1984-85 Los Angeles Lakers

After losing the NBA Finals in seven games to the Boston Celtics a year prior, the Lakers were out seeking revenge in the 1984-85 season. They had a great regular season with a 62-20 record. They then coasted to the NBA Finals -- losing only two games before once again meeting Boston. Despite losing by 34 points in Game 1, the Lakers closed out the Celtics in six, and won the 1985 championship. The “Showtime” Lakers were the greatest show on earth in the ‘80s, and everyone showed up to see the likes of Magic Johnson, Kareem Abdul-Jabbar, James Worthy, Byron Scott, and the rest in purple and gold. This team may have been flashy, but they also had the fight of heavyweight champions. They refused to lose for a second straight year, and truly would not be denied.
