Don Nelson

Donald Arvid Nelson (born May 15, 1940) is an American former professional basketball player and head coach. Nelson is second all-time in regular season wins of any coach in NBA history, with 1,335 (he held the record for most wins for almost 12 years before he was surpassed by Gregg Popovich in 2022). He coached the Milwaukee Bucks, the New York Knicks, the Dallas Mavericks, and the Golden State Warriors. After an All-American career at the University of Iowa, Nelson won five NBA championships playing with the Boston Celtics, with his number 19 retired by the franchise in 1978.

His unique brand of basketball is often referred to as "Nellie Ball". A coaching innovator, Nelson is credited with, among other things, pioneering the concept of the point forward, a tactic which is frequently employed by teams at every level today. He was named one of the Top 10 coaches in NBA history.

On April 7, 2010, Nelson passed Lenny Wilkens for first place on the all-time NBA wins list with his 1,333rd career win. His all-time record coaching record is 1,335–1,063 (.557). He was inducted into the Naismith Basketball Hall of Fame in 2012. Provided by Wikipedia
