The official mascot of the Memphis, Tennessee Grizzlies is a grizzly bear called Grizz. He was introduced in 1995 when the team was located in Vancouver.
The reason is because before the Memphis Grizzlies were in Memphis they were from Vancouver, British Columbia. They got the Grizzly Bear mascot because the Grizzly Bear was Native to the land so they adopted it for their mascot.
