The 2023 NFL season is the year of the backup quarterback. 

Injuries early on, including Aaron Rodgers' devastating Achilles injury just four plays into his debut with the New York Jets in Week 1, and lackluster performances by others have led to a busy quarterback carousel this year. 

Some familiar faces have returned to the field, while other, lesser known players have stepped into the spotlight.

Will Levis was passed over in the first round of the 2023 NFL Draft. Looking back, several NFL teams may be dealing with a bit of regret. 

The former Kentucky quarterback started out the season as the third-string quarterback behind veteran Ryan Tannehill. But after Tannehill left with a high ankle sprain in the Titans’ loss to the Baltimore Ravens, Levis was bumped up behind Malik Willis. 

Ahead of Tennessee's next matchup, head coach Mike Vrabel announced the rookie second-round pick would take over as the team’s starting quarterback, a position he’s maintained through Week 15. 

Levis is 3-4 as a starter and has completed 130 passes for 1,593 yards and eight touchdowns and thrown three interceptions. He has kept the Titans' playoff hopes alive, most recently with an improbable comeback victory over the Miami Dolphins Monday night.
