After serving in the
United States Navy from 1942 to 1946, Newell was appointed head men's basketball coach at the
University of San Francisco in 1946. During his four-year tenure at USF, Newell compiled a 70–37 record and coached the
Dons to the
1949 National Invitation Tournament championship. In 1950 he accepted an appointment as head coach at Michigan State University, where he stayed until 1954. Newell returned to the West Coast in 1954 when he was hired as head coach at the University of California, Berkeley. Newell was very successful at Cal, compiling a record, winning four consecutive
PCC/
AAWU titles from 1957 to 1960, and leading the Golden Bears to two straight appearances in the
NCAA tournament championship game—which they won in
1959. Newell himself earned
national Coach of the Year honors in 1960. At Berkeley, he became a faculty initiate of the Nu chapter of
Phi Kappa Tau fraternity where player
Darrall Imhoff was a member. Newell also coached the
U.S. men's Olympic basketball team to a gold medal in the
1960 Summer Olympics in
Rome, leading a talented squad that featured future National Basketball Association (NBA) stars and Hall of Famers
Walt Bellamy,
Oscar Robertson,
Jerry West, and
Jerry Lucas. His win in the Olympics made him one of only three coaches to win the "Triple Crown" of NIT, NCAA, and Olympic championships. Newell is also known to have introduced the reverse-action offense in the late 1950s. After being advised by doctors to give up coaching because of stress, he served as the
Athletic Director at Cal from 1960 to 1968. Among his various achievements includes having a slight winning record against UCLA head coach
John Wooden, their head-to-head record was in Newell's favor; he is considered by some to be the greatest coach in college basketball history. ==NBA work==
