Nicknamed "Snoop",[1] he played college football for the Utah Utes, leading them to Pac-12 South Division titles in 2018 and 2019.

Huntley was signed by the Baltimore Ravens as an undrafted free agent in 2020, earning Pro Bowl honors in 2022 while starting four games in place of injured starter Lamar Jackson.

[7] Huntley started the first nine games of his junior year in 2018, missing the last five due to injury,[8] finishing the season by completing 150 of 234 passes for 1,788 yards, 12 touchdowns and six interceptions.

[23][24] Huntley got his first NFL start on November 21, 2021, when Jackson was not able to play due to a non-Covid illness against the Chicago Bears.

[25][26] In Week 14 against the Browns, following Jackson's injury late in the first quarter, Huntley came into the game, completed 27 of 38 passes for 270 yards and a touchdown, and almost led the Ravens to a comeback win, narrowly losing 22–24.

On December 30, 2021, Huntley was activated[30] and named the starter for the Ravens against the Los Angeles Rams and the Steelers in Weeks 17 and 18 respectively.

In a low-scoring affair, Huntley led a game-winning drive in the final three minutes that he capped off with a two-yard touchdown run for the 10–9 win.

[35] He started in Week 14 against the Pittsburgh Steelers, but was knocked out of the game in the third quarter with a concussion and replaced by Anthony Brown, although the Ravens would still win 16–14.

[39] On January 31, 2023, Huntley was named to the 2023 Pro Bowl as an injury replacement for Bills quarterback Josh Allen.

[40] His selection was met with considerable shock and questions as to its worthiness, owing to his comparatively poor regular-season statistics, as well as a small sample size of just four games as a starter.

[51] Following an injury to Thompson, Huntley was named the starter for the Dolphins' Week 4 game against the Tennessee Titans, with Boyle serving as his backup.
