2001–02 Memphis Grizzlies season: The 2001–02 NBA season was the Grizzlies 7th season in the National Basketball Association, and their first season in Memphis.  After six years of struggling in Vancouver, the Grizzlies relocated to Memphis.  Although it was the first NBA team for the city, Memphis played home to an American Basketball Association team from 1970–1975.  During the offseason, the Grizzlies acquired rookie Pau Gasol, Brevin Knight and former University of Memphis star Lorenzen Wright from the Atlanta Hawks, while acquiring Jason Williams and Nick Anderson from the Sacramento Kings.  However, Bryant Reeves missed the entire season due to a preseason back injury, and retired after playing just six seasons in the NBA, while Michael Dickerson played just four games due to a groin injury.

The Hawks remain the only sports franchise ever based in Iowa from any of the current Big Four Leagues.

He began shooting the first jumpers seen around the Great Lakes in December 1937 in his high school gym in Gary.  By 1941, the shot was so unstoppable he used it to take the Froebel High School Blue Devils all the way to the Final Four of the Indiana state tournament, the "mother of them all."  Eventually, he starred with the old Oakland Bittners of the AAU, and he was one of the first blacks signed in the NBA.  Minor died in 1998.
