from a "howling bear" to a more stoic bear head. In 2009, the Grizzlies released an alternate uniform with Beale Street blue as the base color. Unlike the primary uniforms, this design featured the city name and player's name arranged in a straight alignment; the primaries had a radially arched alignment. When the Grizzlies switched to Adidas' Revolution 30 system in 2010, the numbers changed from a split-letter style to a bolder, single-color style, presumably due to the difficulty of producing such design. In 2017, the Grizzlies wore a black sleeved uniform as a tribute to Martin Luther King Jr. After switching to Nike in 2017, the Grizzlies made minimal changes to their uniforms, with the exception of the Beale Street alternates now featuring the player's name below the number. However, the following season, the Grizzlies drastically changed their uniforms. The white "Association" and navy blue "Icon" uniform featured player names below the number and straight alignment for the city name and team name respectively. Both uniforms featured three alternating lines on the beltline, which spelled "MEM", the primary logo on the left leg, and asymmetrical striping. On the Beale Street blue "Statement" uniform, player names were placed above the number, and the team name was arranged in a radial arch. The primary logo is on the beltline and on the left leg while the aforementioned alternating "MEM" lines surround the logo. In 2022, the "Statement" uniform was modified, featuring the full team name ("Memphis" in gold, "Grizzlies" in navy/smoke/navy split letters) in front, the primary logo on the right leg, and "MEM" lines on the striping and beltline. As part of the Nike contract, the Grizzlies also wore a fourth uniform, the "City" uniform. The original "City" uniform had a white base and featured lettering based on the "I am a Man" protest banners from the Memphis sanitation strike of 1968. The 2018–19 "City" uniform, which featured a grey base and gold letters, paid tribute to professional wrestling in Memphis. The Grizzlies did not wear a "City" uniform for the 2019–20 season, opting for the throwback Vancouver Grizzlies uniforms instead. In the 2020–21 season, the Grizzlies returned to wearing "City" uniforms, this time with a black base, metallic gold lettering and turquoise trim as a tribute to Isaac Hayes and Stax Records. In the 2021–22 season, the Grizzlies wore a commemorative "City" uniform featuring a mix of styles used
