J.J. McCarthy vs. Carson Wentz: Who Is Vikings QB2?

The direct answer: J.J. McCarthy still has the stronger developmental claim to Minnesota's backup quarterback job, but Carson Wentz has made it a real late-preseason decision. McCarthy and Wentz split second-team repetitions during Tuesday's 80-minute practice, according to ESPN reporter Kevin Seifert. That is a meaningful change from the earlier camp structure, but it is not yet an official demotion or roster decision.
NBC Sports summarized the rep split after McCarthy's uneven preseason showing against Baltimore. He completed 5 of 10 passes for 81 yards, missed two visible opportunities and left after the first quarter while appearing hobbled. Minnesota did not announce a significant new injury, so the competition should be evaluated primarily as a performance and trust question.
How Minnesota arrived at a QB2 battle
Kyler Murray won the starting job earlier in August, moving McCarthy from a QB1 competition into a backup role. ESPN's review of the decision reported that coach Kevin O'Connell still believes McCarthy has a future with the organization. At that point, Wentz had generally worked as the third quarterback. Splitting the second-team work now signals that Minnesota wants a fresh comparison before the roster deadline.
Wentz offers a different form of security. He played five games as Minnesota's starter in 2025 before a shoulder injury ended his season, and he returned in March with a full offseason to learn the system. The Vikings' signing announcement described the move as additional strength for a room that already included Murray and McCarthy.
Quarterback | 2025 starts | Completion rate | Pass yards | TD-INT |
|---|---|---|---|---|
J.J. McCarthy | 10 | 57.6% | 1,632 | 11-12 |
Carson Wentz | 5 | 65.1% | 1,216 | 6-5 |

The case for McCarthy
McCarthy is 23, was selected 10th overall in 2024 and remains under a fully guaranteed rookie contract through 2027. His ceiling, athleticism and familiarity with O'Connell's long-term development plan are legitimate reasons to keep him second. The strongest counterpoint is accuracy. Minnesota cannot treat draft status as a substitute for dependable ball placement if one play forces the backup into a regular-season game.
The case for Wentz
Wentz is the more experienced emergency option. He has operated this offense in regular-season games, completed 65.1 percent of his throws last year and has 103 career appearances. His value is predictability: the staff knows how he prepares, what he can execute and how the offense changes around him. The downside is that a veteran QB2 choice reduces the live reps available for McCarthy's development and could accelerate questions about McCarthy's future.
What coaches actually judge in a backup
The decision is broader than preseason passer rating. A backup must set protections, communicate motions, manage the play clock, avoid catastrophic turnovers and enter with little warning. McCarthy can win the job by showing that his operation remains calm even when individual throws miss. Wentz can win it by proving his experience produces cleaner decisions without sacrificing the explosive elements O'Connell wants. Practice reps with the same supporting unit give Minnesota its fairest side-by-side comparison.
Minnesota must also decide how it wants the weekly quarterback room to function. A veteran backup can help Murray diagnose opponents and prepare for unusual pressure looks, while a younger backup needs practice snaps to keep developing. That tension makes the QB2 decision both a Sunday insurance choice and a long-term resource allocation choice.
Could Minnesota trade or waive McCarthy?
A transaction is possible, but it should not be reported as decided. McCarthy's guaranteed compensation makes a trade more complicated because an acquiring team would evaluate both the player and the money. Waiving him would also expose a former top-10 pick to the rest of the league. Minnesota can keep three quarterbacks, but every extra quarterback consumes a roster spot during a cutdown week when special teams and injury depth matter.
The broader roster pressure is explained in Football Nation's 2026 cutdown deadline guide. The same evaluation logic shaped the Cowboys' Joe Milton versus Sam Howell battle and Carolina's Bryce Young franchise-quarterback decision.

The next checkpoint
The preseason finale against Denver is the clearest remaining on-field test. Watch who enters after Murray, who receives work with the second offensive line and whether McCarthy's accuracy improves when he is asked to vary pace instead of driving every throw. The next decisive checkpoint comes Sunday, when Minnesota must reduce the roster to 53 players.
Football Nation takeaway
McCarthy should be considered the slight QB2 favorite because of age, contract and organizational investment. Wentz is the safer one-game substitute today. If Minnesota prioritizes immediate stability, Wentz can win the role. If it prioritizes McCarthy's development and future value, he stays second. The rep split tells us the answer is no longer automatic; it does not tell us the decision has already been made.
