NFL preseason backup quarterbacks may be one of the most overlooked pieces of preseason handicapping. Bettors naturally focus on starters, but a starting quarterback might play only one or two drives while QB2 and QB3 control most of the game. In August, understanding the entire quarterback room can sometimes tell you more about a matchup than simply knowing which team has the better starter.
Why Backup Quarterbacks Matter So Much
Regular-season football is built around the starter.
Preseason football is different.
A starting quarterback may play:
- One possession
- One quarter
- A handful of series
- Or not play at all
That means most of the offensive snaps can belong to backups.
If one team has an experienced QB2 capable of running the offense while the opponent turns to an inexperienced third-stringer, the matchup can change dramatically once the starters leave.
The Raiders Just Gave Us A Perfect Example
Las Vegas provided a great example against Houston.
Rookie Fernando Mendoza started and struggled early as the Raiders fell behind 20-3 at halftime. Backup quarterback Aidan O'Connell then helped lead the comeback, finishing with 166 passing yards and directing a 96-yard game-winning drive as Las Vegas won 22-20.
That is exactly why preseason quarterback depth matters.
The starter influenced the first half.
The backup helped decide the game.
FeedMe Lesson
When handicapping preseason football, do not stop at:
“Who is starting?”
Also ask:
“Who plays when the starter leaves?”
Experienced Backups Can Change A Total
Backup quarterbacks can be especially important when betting totals.
A capable veteran may keep an offense moving instead of allowing the game to turn into:
punt → punt → turnover → punt
Denver recently received 131 passing yards and a touchdown from Jarrett Stidham in a preseason win over Atlanta. Chicago veteran Case Keenum also produced 151 yards and two touchdowns in a preseason victory over Cleveland.
Those performances matter because second-unit production can keep scoring alive long after the starters have left.
What To Look For In A Backup QB
Not all backups should be evaluated the same way.
Experience
A veteran who has started regular-season NFL games may be much more comfortable handling preseason situations than a developmental rookie.
System Familiarity
How long has the quarterback been in the offense?
Knowing the terminology, protection calls, and timing can make a major difference.
Mobility
Mobile quarterbacks can extend drives when backup offensive lines break down.
Decision Making
A quarterback who protects the football can keep field position from swinging dramatically.
Supporting Cast
The quarterback still needs protection and receivers capable of creating opportunities.
A good QB2 behind a poor second-unit offensive line may still struggle.
QB2 Can Matter More Than QB1
This sounds strange, but there are preseason games where the backup quarterback deserves more weight in the handicap than the starter.
Imagine:
Team A
Starter plays 10 snaps.
Backup plays 35 snaps.
Team B
Starter plays 12 snaps.
Backup and third-string quarterback combine for 40 snaps.
Which quarterback has more opportunity to influence the final score?
Probably not the starter.
That is why preseason analysis should focus on expected snap distribution, not simply name recognition.
Quarterback Competitions Create Another Angle
Preseason quarterback battles can also create motivation.
A player competing for a starting job or roster position has every reason to push the offense.
Las Vegas is currently evaluating Fernando Mendoza alongside veteran Kirk Cousins, with the Raiders still not publicly settling the competition after Mendoza's mixed outing against Houston.
Cleveland has also used preseason games as part of its quarterback evaluation, with NFL.com highlighting its ongoing competition during August.
Those situations matter because playing time and offensive intent can be different from teams whose quarterback depth chart is already completely settled.
What FeedMe Checks Before Betting
Before taking a preseason side or total, look at the complete quarterback rotation:
- Who starts?
- How long is the starter expected to play?
- Who is QB2?
- Who gets the second half?
- Does the backup have NFL experience?
- Is there an active quarterback competition?
- Which offensive line will protect him?
- Has the market already reacted to the information?
This gives a much better picture than simply comparing the two starting quarterbacks.
The Biggest Mistake: Ignoring The Second Half
A bettor might correctly handicap the first quarter and still lose the game.
That happens constantly in preseason.
Your team can lead 14-3 while the starters are playing and still lose after inexperienced backups enter.
The reverse can happen too.
A team can struggle early and completely change the game with superior depth.
Preseason bets are graded on the final score.
Your handicap needs to account for all four quarters.
Final Take
NFL preseason backup quarterbacks deserve much more attention than they usually receive.
The starter gets the headlines, but the backup often gets the snaps that decide the spread and total.
Before betting an August matchup, look beyond QB1.
Study the rotation. Compare experience. Understand playing time. Look at the supporting cast.
Because in preseason football:
QB1 may start the game. QB2 may decide your bet.
