Quarterbacks may be the driving force of the NFL; having one of the game's few elite signal-callers is often the difference between contending for the playoffs and contending for a Lombardi Trophy. However, football is a team sport, which means the QBs still require help on both sides of the ball. And there are plenty of important pieces at other premium positions.

With that in mind, here's a look at one non-QB each team can least afford to lose in 2023:

Arizona Cardinals: OT D.J. Humphries

Presumably, they'll already be down QB Kyler Murray at the start of the year. Losing their most accomplished tackle, whose injury-related absence in 2022 helped fuel offensive dysfunction, would put the next QB in danger as well.

Atlanta Falcons: OT Jake Matthews

With Tyler Allgeier behind rookie Bijan Robinson and Jonnu Smith now behind Kyle Pitts, neither RB nor TE is short on depth. Young QB Desmond Ridder needs to stay upright to feed the weapons, however, and Matthews is a solid blind-side bodyguard.

Baltimore Ravens: C Tyler Linderbaum

New WR Odell Beckham Jr. is already an injury risk, but Lamar Jackson's chief concern in 2023 is staying on the field. Linderbaum was an underrated rookie cog up front, and he's instrumental to their ground attack as the QB of the line.

Buffalo Bills: WR Stefon Diggs

This is why his reported offseason frustrations with Buffalo were such a concern. Without his killer route-running and alpha mentality, Josh Allen has only the mercurial Gabe Davis as a proven WR weapon, though rookie TE Dalton Kincaid could help.
