The Dallas Cowboys face a critical decision at backup quarterback as rookie Joe Milton’s uneven preseason fuels debate. While his cannon arm and adoption of Dak Prescott’s signature cadence show promise, mechanical inconsistencies raise concerns about his readiness.
With Prescott’s injury history and a tight championship window, Dallas cannot afford unreliable QB2 play. Veterans like Case Keenum remain available, but the organization must determine if Milton’s potential outweighs immediate risks in the coming weeks.
The Cowboys’ playoff hopes may hinge on resolving this dilemma before Week 1, especially in a division where every game matters.
- Joe Milton’s preseason performance (58.6% completion, 1 TD/1 INT) raises concerns about his readiness as Dak Prescott’s primary backup.
- Dallas faces urgent QB2 decisions with Prescott’s injury history (12 missed games since 2020) threatening playoff ambitions.
- The Cowboys are weighing Milton’s upside against veteran free agents like Case Keenum or Nick Foles, despite limited cap space ($6.2M).
- Cooper Rush’s success in Baltimore (71% preseason completion) highlights Dallas’ potential QB2 misstep in roster construction.
Dak Prescott’s Backup QB Dilemma: Can Joe Milton Secure the Role or Will Dallas Chase Veteran Support?
The Dallas Cowboys find themselves at a crossroads with their backup quarterback situation as rookie Joe Milton’s preseason performance sparks intense debate. While the strong-armed prospect displayed flashes of his undeniable physical gifts, his inconsistency has led many to question whether Dallas should pursue a veteran insurance policy behind franchise quarterback Dak Prescott.
Through two preseason games, Milton has completed just 58.6% of his passes with one touchdown and one interception, resulting in a pedestrian 68.6 passer rating. His struggles with accuracy, particularly on intermediate routes, have been glaring. The coaching staff has given him extensive opportunities (over 50 total attempts), yet his completion percentage remains well below the NFL’s backup QB standard of 65%.
Prescott’s injury history makes the backup role particularly crucial for a Cowboys team with Super Bowl aspirations. Since 2020, Prescott has missed 12 games due to various ailments, including last season’s ankle scare that sidelined him for three weeks. During that stretch, Dallas went just 1-2 without reliable QB play.
Breaking Down Milton’s Preseason Struggles
Several key issues have hampered Milton’s transition to the NFL:
- Footwork breakdowns: Frequently throws off back foot when pressured
- Slow processing: Took 3+ seconds on 42% of dropbacks
- Deep ball reliance: 78% of completions came on throws over 15 yards
Cooper Rush’s Success in Baltimore Highlights Cowboys’ Potential Mistake


The decision to let Cooper Rush depart in free agency looks increasingly questionable as the former Cowboys backup thrives in Baltimore. Rush, who compiled a 9-5 record as Prescott’s understudy since 2018, has seamlessly adapted to the Ravens’ system, completing 71% of his preseason passes with zero turnovers.
Rush’s success highlights what Dallas currently lacks – a game manager who protects the football and executes the offense efficiently. His career 2.1% interception rate would provide crucial stability if Prescott were to miss time. Meanwhile, the Cowboys are left gambling on Milton’s untested potential.



Comparing Key Backup QB Metrics
| Quarterback | Comp % | TD-INT | Passer Rating |
|---|---|---|---|
| Joe Milton (2024) | 58.6% | 1-1 | 68.6 |
| Cooper Rush (2024) | 71.0% | 1-0 | 94.3 |
| Will Grier (Career) | 53.8% | 0-4 | 56.2 |
Available Veteran Options for Dallas to Consider
If Dallas decides Milton isn’t ready, several experienced quarterbacks remain available:
- Case Keenum: 62 career starts including playoff experience
- Nick Foles: Super Bowl MVP knows NFC East defenses
- Colt McCoy: Career 63.3% completion percentage
Financial constraints could complicate any signing, as Dallas has just $6.2 million in cap space. However, the Cowboys have traditionally addressed backup QB late in preseason, such as when they signed Rush after final cuts in 2021.



The Will Grier Conundrum: Why Isn’t Dallas Considering Him?


Will Grier’s complete absence from the backup conversation remains puzzling. Despite being on the roster since 2023 and having more NFL experience than Milton, the former third-round pick received just 12 snaps in the preseason opener.
Grier’s career numbers (53.8% completion, 4.6% INT rate) certainly don’t inspire confidence, but his familiarity with the system and mobility could make him a safer short-term option than Milton. The coaching staff’s refusal to give him meaningful reps suggests they view him strictly as an emergency QB3.
Grier’s Limited Opportunities
- 12 total preseason snaps (all cleanup duty)
- 0 first-team practice reps in training camp
- Only 2 career starts, both in 2019
Dak Prescott’s Injury History Raises Stakes
Prescott’s medical chart underscores why Dallas can’t afford to gamble at backup QB:
- 2020: Season-ending ankle fracture (11 games missed)
- 2022: Thumb surgery (5 games missed)
- 2023: Ankle sprain (3 games missed)



The Path Forward: Dallas’ Three Potential Solutions
As final roster cuts approach, the Cowboys essentially have three options:
- Commit to Milton: Accept growing pains for long-term payoff
- Sign a veteran: Keenum or Foles provide immediate stability
- Trade for depth: Explore options like Packers’ Sean Clifford
Owner Jerry Jones typically makes quarterback decisions personally, and his recent comments suggest Milton will get every opportunity: “We see special traits in Joe that remind us of a young Dak.” However, with five preseason quarters remaining, the clock is ticking for Milton to prove he’s ready.



Key Dates to Watch
- August 24: Final preseason game
- August 27: Roster cut deadline
- August 29: Veteran free agents become more affordable
