Naismith Basketball Hall of Famer Wes Unseld has died at the age of 74 after a bout of pneumonia, the Washington Wizards announced on Tuesday.

The Louisville native spent all 13 of his NBA seasons with the Baltimore/Washington Bullets franchise.

"He was the rock of our family – an extremely devoted patriarch who reveled in being with his wife, children, friends and teammates," Unseld's family said in a statement. "He was our hero and loved playing and working around the game of basketball for the cities of Baltimore and Washington D.C., cities he proudly wore on his chest for so many years."

Unseld appeared in a Bullets/Wizards franchise record 984 games, averaging 10.8 points and 14.8 rebounds over his career.

Taken with the second pick of the 1968 NBA Draft out of Louisville, Unseld, a five-time All-Star, won both Rookie of the Year and Most Valuable Player in 1969.

“We all admired Wes as the pillar of this franchise for so long, but it was his work off the court that will truly leave an impactful legacy and live on through the many people he touched and influenced throughout his life of basketball and beyond," Wizards owner Ted Leonsis said in a statement.

Upon his retirement, Unseld joined the organization's front office, becoming the team's vice-president in 1981. In 1988, Unseld became the Bullets head coach, resigning in 1994.

He was elected to the Hall of Fame in 1988 and to the College Basketball Hall of Fame in 2005.
