Doug Collins is well aware of Michael Jordan's greatness, which he highlighted in the ESPN docu-series about the Chicago Bulls, “The Last Dance.”

The former NBA player and bench tactician coached Jordan and the Bulls from 1986 until 1989 and was able to see first hand why most people call Jordan the greatest basketball player of all time. When discussing the greatness of his former player, Collins had a clear opinion.

“I coached him for three years. From the '86-'87 season through '88-'89. When I was coaching him, he was the MVP of the league, he was the MVP of the All-Star game, he won the slam dunk competition and he was the Defensive Player of the Year. That's greatness,” Doug Collins said in Episode 3 of “The Last Dance.”

During the three years under Collins, Jordan averaged an astounding 34.9 points, 6.2 rebounds, 6.2 assists, 3.0 steals and 1.0 blocks per game. MJ also shot 51.6 percent from the field and winning the NBA scoring title all three seasons.

However, despite Jordan's incredible production early in his career, Collins was just 137-109 as the Bulls' head coach. He was fired in the summer of 1989 after the team reached the Eastern Conference Finals just once during his tenure and lost to the Detroit Pistons in that series.

More recently, Collins was the head coach of the Philadelphia 76ers from 2010-2013, but he once again failed to produce more than an above-average Eastern Conference team.

It remains to be seen what other revelations Doug Collins will provide in “The Last Dance,” but it's definitely always interesting to hear from those who witnessed it how Michael Jordan dominated in the NBA.
