J.J. McCarthy

QB · MIN Vikings

A lost rookie season removes the one year the league lets a quarterback learn cheaply, and it also removes the evidence anyone would use to price him. What the small precedent group shows is that the missing year is not itself predictive: the same starting condition produced an MVP-caliber season, a slow burn and a bust. It means his 2025 line, not his draft slot, is the only real information available.

The debut that took two years

Four first-round quarterbacks since 1999 threw zero passes as rookies and then got the job in year two. Their year-two seasons ranged from 338 fantasy points to 91.

First-round QBs since 1999 with no pass attempts as a rookie and 200 or more in year two

Quarterback	Drafted	Pick	Year-two attempts	Year-two PPR
Daunte Culpepper	1999	11	474	338.5
Carson Palmer	2003	1	432	158.6
Jason Campbell	2005	25	207	91.1
J.J. McCarthy	2024	10	243	125.4

McCarthy's rookie year does not exist in the record. He threw zero NFL passes in 2024 and made his debut in September 2025, which puts him in a group of four first-round quarterbacks since 1999. The precedents fan out wildly: Culpepper's first season on the job was a 33-touchdown, 338-point monster, Palmer's was a 18-touchdown, 18-interception scuffle he followed with a 32-touchdown year, and Campbell never became more than a caretaker. There is no median outcome here, only three very different ones.

Why it matters. A lost rookie season removes the one year the league lets a quarterback learn cheaply, and it also removes the evidence anyone would use to price him. What the small precedent group shows is that the missing year is not itself predictive: the same starting condition produced an MVP-caliber season, a slow burn and a bust. It means his 2025 line, not his draft slot, is the only real information available.

He threw the highest rate of interceptions in football and Minnesota went 6-4 in his starts anyway.

Minnesota's 2025 season by who started (regular season)

Split	Games	Record	Points scored per game	Points allowed per game
McCarthy starts	10	6-4	19.9	18.1
Anyone else	7	3-4	20.7	21.7

McCarthy gave the ball away on 4.94 percent of his throws, the worst rate in the NFL among quarterbacks with 200 attempts, and Minnesota still won six of his ten starts. The reason is not hidden in his stat line. The Vikings scored 19.9 points a game with him and 20.7 without, essentially the same, while allowing 18.1 with him and 21.7 without. The defense won those games. The rookie mostly did not lose them.

Why it matters. Separating a young quarterback's record from his play is the whole exercise in his second year, because a winning record is the single most common reason a bad process gets extended. Minnesota's split says the offense was the same unit regardless of who took the snaps and the defense was three and a half points better with McCarthy on the field, which is a coincidence of scheduling rather than a quarterback effect. The record is not evidence for him. The 12 interceptions are evidence against.

The picks and the pocket

Sacked on 10 percent of his dropbacks, third-worst in the league. That number tends to follow the quarterback, not the offensive line.

How often a quarterback's sack rate stays on the same side of league average

Measure	Value
Back-to-back seasons compared (300 or more dropbacks each)	534
Landed on the same side of average both years	362 of 534 (67.8%)

McCarthy went down on 27 of his 270 dropbacks, a 10.00 percent sack rate that ranked third-worst in football. The reason that matters more than a typical rookie growth stat: sack rate is one of the stickiest things a quarterback owns. Across 534 back-to-back seasons in the data, 67.8 percent of passers landed on the same side of league average two years running, even as their offensive lines turned over around them. Whatever combination of holding the ball and missing the hot read produced this, the record says it is his to fix rather than his line's.

Why it matters. Sacks are the most expensive negative play in football because they cost yardage, down and clock at once, and they are the leading cause of quarterback fumbles. For a passer already giving the ball away at a league-worst interception rate, a 10 percent sack rate compounds the problem rather than sitting beside it. It is also the number with the strongest claim to persist into 2026, which makes it the most important thing on his tape this offseason.

Four rushing touchdowns in ten games, the sixth-best rate in the league. It is the best number on his page.

Strip away the passing and one number survives. McCarthy scored four rushing touchdowns in ten games, a rate that put him sixth in the league and ahead of Bo Nix, Patrick Mahomes and Drake Maye. He did it on only 181 rushing yards, which means these were short-yardage keepers rather than scrambles: he is a quarterback the staff will run near the goal line. In fantasy terms four rushing scores are worth 24 points, roughly a fifth of his entire season total of 125.4.

Why it matters. Rushing touchdowns are the cheapest points available to a fantasy quarterback and the single biggest reason two passers with similar throwing lines finish 10 spots apart. For McCarthy specifically they are also the only piece of his 2025 that a fantasy manager can currently count on, given that the completion percentage, the interception rate and the sack rate all ranked near the bottom of the league. If the throwing improves at all, the goal-line role is already in place.

He debuted inside the 30th-busiest offense in football, and the one that got the least out of every snap in his division.

J.J. McCarthy	243	1,632	11	12
Carson Wentz	169	1,216	6	5
Max Brosmer	71	328	0	4

Minnesota ran 943 offensive plays, 30th in the league, and lost 0.115 expected points on every one of them, 28th. Both figures were the worst in the NFC North by a distance: Chicago ran 153 more plays and Green Bay was worth a quarter of a point more per snap. Three different quarterbacks threw a pass for the Vikings, and none of them cleared a touchdown-to-interception ratio of 1.5. This is the environment McCarthy's rookie line came out of, and it is the piece most likely to look different in 2026.

Why it matters. Offensive snap volume is a coaching and game-script property that sets the ceiling on every skill player and quarterback attached to it, and Minnesota supplied the smallest one in its division. It matters for reading McCarthy in two directions: it partly excuses the raw totals, and it caps what a good version of him would even be worth in fantasy terms next season. A quarterback in the 30th-busiest offense needs elite efficiency to matter, and that is a long way from where he finished.

The 2026 file

MYTH TEST: the second-year leap. It is real, it is small, and one passer in four comes back worse.

J.J. McCarthy's 2025, week by week (regular season)

1	CHI	13/20	143	2	1	22.2
2	ATL	11/21	158	0	2	2.8
9	DET	14/25	143	2	1	18.9
10	BAL	20/42	248	1	2	14.7

14	WAS	16/23	163	3	0	20.4
15	DAL	15/24	250	2	1	23.5
16	NYG	9/14	108	0	1	8.3
18	GB	14/23	182	0	0	8.0

Every August somebody promises that a young quarterback is about to explode in year two. On average that season really is better than the first, but the gain is a couple of points of efficiency, not a transformation, and about one passer in four comes back worse. McCarthy's own weekly log is the argument for patience over prophecy: five of his ten starts produced fewer than 9 fantasy points and four produced 18 or more, and in three straight starts he went 0.5, 20.4 and 23.5. The volatility, not the average, is the tell for how far he has to go.

Why it matters. The second-year narrative persists because the visible examples are the ones who leapt, while the quarterbacks who stalled disappear from the conversation. Applying it to McCarthy needs an extra caveat: 2026 will be his second season of actual football but his third year in the building, so the usual mechanism, a full offseason as the starter with a year of live reps behind him, does at least apply for the first time. What history says it buys is a step, not a leap.
