Coming in at Number 9 on our list is Dan Roundfield. The Power Forward stood at just 6’8″, but that did not stop him from being a force on the boards. Roundfield played six seasons for the Hawks, and was a walking double-double in each season he spent in Atlanta. Over his six-year tenure with the team, he averaged 17.7 points and 10.7 rebounds per game. He made three All-Star appearances over this time, the only times he retrieved this accolade in his career. Though his numbers are impressive, a lot of Roundfield’s success does not show up on the stat sheet. Roundfield was one of the best defensive players the franchise has ever seen. He made the NBA All-Defense First Team three times during his six-year span with the team, and also made the NBA All-Defense Second Team twice. He made the All-NBA Second Team in 1980. With all this being said, it’s clear that Roundfield is one of the best to don the Hawks’ uniform. Unfortunately, Dr. Rounds passed away in an incident in 2012 when he drowned in Aruba. May he rest in peace.
