JJ McCarthy Biography: From No. 10 Pick to Giants Backup, Full Career Breakdown

JJ McCarthy Facts Box

A player the Minnesota Vikings once traded up to select in the first round of the 2024 draft has now been sent away for a single fifth round pick in 2027. That is the price the New York Giants paid for JJ McCarthy, and his cap number is small: just under $1 million this season, rising to $3.77 million next year because of a $2.585 million roster bonus. For a former top ten selection, it is a strikingly low figure.

McCarthy arrives in New York as a backup. Giants head coach John Harbaugh has said Jameis Winston remains the starting quarterback, even after the trade, while McCarthy learns the offense. In Minnesota he had slipped to third string behind Kyler Murray and Carson Wentz after losing the training camp competition. His recent form is the reason the deal was possible: a difficult 2025, a lost preseason battle, and a fresh start with a team that badly needs quarterback help after Jaxson Dart went down with a season ending knee injury in Week 2.

Here is the full story of the JJ McCarthy trade, his contract, and how a Michigan national champion reached this point, season by season.

Michigan Wolverines, 2021 and 2022: The Rise

Long before the NFL, McCarthy was one of the most decorated high school quarterbacks in the country. A five star recruit, he won a national championship at IMG Academy in Florida in 2020 with an 8 and 0 team, then committed to Michigan and head coach Jim Harbaugh.

His 2021 season was mostly a backup role behind Cade McNamara, but the Orange Bowl performance against Georgia changed the conversation. Many people inside and around the program believed his showing and his pedigree meant he would win the starting job in 2022, and he did. That year McCarthy took over a Michigan offense that leaned heavily on the running game, with Blake Corum carrying much of the load. Michigan reached the College Football Playoff again, and McCarthy became a recognizable name nationally, along with his open dislike of rival Ohio State.

Michigan Wolverines, 2023: The National Championship Campaign

The 2023 season is the foundation of the McCarthy story. Michigan went unbeaten, won the Big Ten, and defeated Washington in the national championship game. McCarthy completed a high percentage of his passes for roughly 3,000 yards with more than twenty touchdowns and only a handful of interceptions, all while playing efficient, mistake free football in a system built around the run.

That context matters for scouting. Supporters pointed to his winning résumé, his mobility, his arm strength and his leadership. Critics pointed out that he was rarely asked to throw the ball 35 or 40 times a game, so the sample of high volume passing was small. When the Vikings selected him tenth overall, plenty of analysts around the league raised their eyebrows. Notably, the Giants scouted him heavily and even considered taking him at pick six, before choosing wide receiver Malik Nabers instead.

2024 NFL Draft and a Lost Rookie Year

Minnesota moved up to draft McCarthy at No. 10, making him the first Michigan offensive player the Vikings had ever drafted and the first Wolverine they took since Josh Metellus in 2020. The plan was simple: let the young quarterback learn behind Sam Darnold, with head coach Kevin O’Connell shaping the offense and stars such as Justin Jefferson and Jordan Addison at receiver.

That plan collapsed quickly. McCarthy suffered a knee injury in the first preseason game, required meniscus surgery, and spent his entire rookie season on injured reserve. Darnold stepped in and played well enough that Minnesota won games and the quarterback of the future never saw the field. It was a redshirt year in the truest sense, and it left an open question about how good McCarthy actually was against NFL defenses.

2025 Season: First Starts and Mixed Results

When Darnold left in free agency, McCarthy was named the starter. He made history in Week 1, becoming the first Vikings quarterback to debut and start in a season opener. He also earned NFC Offensive Player of the Week for helping the team complete a comeback win.

After that promising beginning, injuries and inconsistency took over. He started 10 games and went 6 and 4, finishing 140 of 243 for 1,632 yards, 11 touchdowns and 12 interceptions, with a 72.6 passer rating. Those numbers are the core of the “draft bust” debate that followed him around. The turnover total was the main concern, and the timing was painful because Darnold went on to win a Super Bowl with Seattle.

There was a real positive at the end, though. Over his final four starts, McCarthy completed 54 of 84 passes, a 64.3 percent rate, for 703 yards, five touchdowns and two interceptions, producing a 100.4 passer rating. Fans who believe in the young quarterback point to that stretch as proof that the ceiling was still intact.

2026 Season: Training Camp Loss and the Giants Trade

The Vikings did not wait to see whether that late form would carry over. They signed free agent Kyler Murray, and McCarthy competed with him throughout offseason workouts and training camp. On August 11, O’Connell named Murray the starter. Minnesota then opened the season 3 and 0, which meant McCarthy was not going to see the field any time soon.

Meanwhile, New York’s season took a hard turn. Jaxson Dart suffered a knee injury in Week 2 and was lost for the year. Winston, who had signed a two year, $13 million extension only 22 days earlier, struggled in relief, and the Giants offense had trouble moving the ball. The front office moved quickly, sending a 2027 fifth round pick to Minnesota, subject to McCarthy passing a physical.

Harbaugh reportedly called his brother Jim, McCarthy’s former college coach and now the Chargers head coach, to gather information. Publicly, Harbaugh has been direct about the depth chart, saying Winston is the starter and that the team is moving forward that way. Reaction has been split. Some analysts argue Minnesota got fair value for a player who had fallen out of favor, and that a fifth round pick for a mobile quarterback is a smart low risk gamble. Others say the Giants undercut themselves by extending Winston and then immediately shopping for his replacement.

What Comes Next for JJ McCarthy

The immediate outlook is simple. McCarthy will learn the Giants system, back up Winston, and wait for an opening. If Winston continues to struggle, the coaching staff has an obvious alternative already on the roster. The offense may also be tailored to fit a quarterback who can move, which is exactly where McCarthy is at his best.

The longer term picture depends on the 2027 roster decision, when his $2.585 million roster bonus comes into play and the Giants must decide whether he is part of the plan. His contract is cheap enough that patience carries little risk, and the situation is far better than being buried behind two veterans in Minnesota.

JJ McCarthy still owns a national championship, a top ten draft slot and a strong finish to his first real NFL stretch. He also owns a modest sample, a turnover problem and a lot of doubt. The next several months in New York will go a long way toward answering which version of him is real.
