The 10 Greatest Bulls in history, ranked by Player Efficiency Rating (PER)

9. Jimmy Butler - 19.3

Though Jimmy Butler has played his last seven years on other teams, he had a hell of a run with the Bulls. In his six-year tenure with the Bulls, he was only a starter for four of those years. As a starter, he made three all-star appearances and four all-defensive teams.

He wasn’t the most efficient shooter, but he significantly impacts both sides of the ball. Along with four straight all-defensive seasons, he had three straight seasons averaging 20 or more points. Having a high PER makes a lot of sense due to his all-around production. He likely would have been much higher on the list if he was more productive in his rookie and sophomore seasons. 

8. Chet Walker - 19.6

Chet Walker is the first of five Hall of Famers on this list. Walker played in Chicago for six years and was very productive. He was a four-time All-Star for the Bulls and averaged 19 or more PPG in all six seasons. He also averaged at least five rebounds per game in every season with Chicago, adding to his production

While Walker is a Hall of Famer, it’s impressive that he made this list. He played in an era without the three-point shot, and defensive stats weren’t recorded until his last two seasons. Walker was, however, very efficient in his production and his shooting.
