Several NFL teams will open the season with veterans behind center and younger options waiting nearby. These three backup quarterbacks may not stay on the sideline once losses, injuries and impatient fan bases enter the picture.
The Las Vegas Raiders did not use the No. 1 overall pick on Fernando Mendoza because they envisioned him holding a clipboard for three years.
Kirk Cousins will open the season as the starter, giving Mendoza time to learn without immediately carrying the franchise. That arrangement makes sense in September. It may become harder to defend by October if Las Vegas begins drifting out of contention.
Mendoza has experienced the expected bumps during his first NFL preseason, particularly when facing pressure. He has also displayed the accuracy and arm talent that convinced the Raiders to build their future around him. His first preseason touchdown came on a six-yard throw to Jack Bech, while an increased workload in practice has included first-team repetitions.
Cousins can delay the transition by winning games. If he struggles, however, Las Vegas will quickly face the obvious question: Why keep the first overall selection on the bench?
Of these three backup quarterbacks, Mendoza has the clearest path toward becoming a starter before midseason.

Carson Beck entered training camp behind Jacoby Brissett and Gardner Minshew on the Arizona Cardinals’ depth chart. Then he stepped onto the field for the Hall of Fame Game and made the competition considerably more interesting.
Beck completed 15 of 19 passes for 188 yards and one touchdown against the Carolina Panthers. He led two touchdown drives, avoided turnovers and showed impressive composure while operating behind a backup offensive line. One performance does not crown him Arizona’s next franchise quarterback, but it certainly gave the coaching staff something to consider.
Brissett remains the expected Week 1 starter. He is a dependable veteran who can run the offense and prevent Arizona from rushing Beck onto the field. That plan will work until the Cardinals begin losing games or their offense becomes painfully ordinary.
Beck has already shown enough to make fans curious. If he continues developing during practice, Arizona could decide that live repetitions are more valuable than another season spent watching a veteran bridge quarterback.

Shedeur Sanders lost Cleveland’s starting competition after head coach Todd Monken selected Deshaun Watson to lead the Browns into the regular season.
That decision does not guarantee Watson will keep the job.
Sanders and Watson rotated first-team repetitions during training camp, and the competition lasted until late August. Sanders had an uneven preseason, including an interception during Cleveland’s opener, but he remained close enough to the job that Monken needed nearly the entire summer to make his choice.
Watson carries significant financial baggage, an extensive injury history and little recent production that inspires confidence. Cleveland may want its investment to work, but stubbornly protecting a contract will not rescue a sinking season.
Sanders is now listed directly behind Watson. If the Browns stumble early or Watson misses time, Monken will not need to redesign the entire offense around an emergency option. He can turn to a quarterback who already received extensive work with the starters.
None of these backup quarterbacks is guaranteed to take over. Mendoza, Beck and Sanders merely possess something most reserves do not: a realistic opening that could arrive before the season reaches its halfway point.
Shedeur Sanders' timing was perfect on this TD pass ⌚️
