Before this he hosted The Grant Napear Show, at KHTK Sports 1140 in Sacramento, California where he was fired for tweeting "All lives matter, Every Single One" during the George Floyd protest.

He was also the play-by-play announcer for the Sacramento Kings of the National Basketball Association (NBA), but resigned.

A section of Napear's radio show was "Grant's Rant", in which he furiously exclaims into the microphone about everyday things that irritate him, such as obese passengers on airplanes, stop lights at freeway on-ramps, and people asking him if he's ready for Christmas during the holidays.

[3] Napear has been accused of racism by former players for the Sacramento Kings and has come under fire for defending Donald Sterling, the former owner of the Los Angeles Clippers banned from the NBA after making racist remarks.

[5] On May 31, 2020, after the start of the George Floyd protests, Napear was placed on leave by KHTK after he responded on Twitter to former Kings' player DeMarcus Cousins' question regarding Black Lives Matter with the phrase "All lives matter, Every Single One."
