John Harbaugh and the Giants Make Smart Gamble on J.J. McCarthy After Injury Setbacks

The New York Giants have acquired J.J. McCarthy from the Minnesota Vikings for a 2027 fifth-round draft pick, giving head coach John Harbaugh another quarterback option after Jaxson Dart's injury.

The Giants announced the deal on Monday, 28 September, with the trade pending a physical. Dart suffered a knee injury against the Los Angeles Rams, prompting New York to explore quarterback additions.

The Giants then beat the Tennessee Titans 12-7 to improve to 2-1, with Jameis Winston remaining the starter.

McCarthy, 23, brings youth and former first-round pedigree but also uncertainty. Minnesota selected him 10th overall in the 2024 NFL Draft, and he missed his rookie season following knee surgery. He started 10 games in 2025, going 6-4 with 1,632 passing yards, 11 touchdowns and 12 interceptions.

Why John Harbaugh Likes J.J. McCarthy's Talent

Harbaugh said the Giants began looking at quarterback options after Dart was injured, separating the McCarthy move from Winston's performance against Tennessee.

Winston completed 14 of 22 passes for 118 yards without a touchdown or interception in the win. Harbaugh nevertheless made clear that the veteran remains first on the depth chart. 'Jameis is our starting quarterback, that's how we're rolling,' Harbaugh said Monday.

The Giants considered several possibilities before settling on McCarthy. Harbaugh credited general manager Joe Schoen and the scouting department with placing the young quarterback near the top of their evaluations.

'He was a top-10 pick for a reason, and there's plenty of good tape, even in the NFL, out there,' Harbaugh said.

Harbaugh said McCarthy's ability to throw, run and create plays stood out during his review. He was also familiar with McCarthy's college career at Michigan under his brother, Los Angeles Chargers coach Jim Harbaugh.

McCarthy helped Michigan complete an undefeated national championship season before entering the 2024 NFL Draft.

His professional career has been less settled, leaving the Giants to evaluate potential rather than a proven long-term NFL starter. 'I don't think anybody would deny that J.J. McCarthy is a very talented young quarterback,' Harbaugh said.

Jameis Winston Remains the Giants' Starter

The trade does not mean McCarthy will replace Winston immediately. Harbaugh said McCarthy will initially be either the second or third quarterback as he learns the offence.

The coach also declined to look too far ahead at the future quarterback picture. His immediate focus is getting McCarthy familiar with the system while preparing Winston for the next game.

Harbaugh described the learning process as a 'crash course' and said the Giants would give McCarthy extra work. Terminology and protection calls are among the areas he will need to absorb quickly.

Winston also has contractual security beyond this season. The Giants signed him to a two-year, $13 million extension earlier in September, keeping him under contract through 2028.

Dart has been ruled out for the rest of the regular season. Harbaugh has left open the possibility of a postseason return depending on the quarterback's recovery.

That leaves the Giants with a clear short-term hierarchy. Winston remains the starter, McCarthy is learning the system, and Dart remains part of the longer-term picture.

Brian Burns Injury Adds to Giants' Early Adversity

New York is also dealing with a major defensive loss after outside linebacker Brian Burns tore his right ACL against Tennessee. Harbaugh confirmed Monday that Burns will miss the rest of the season.

Burns' injury adds pressure to a 2-1 team, but it didn't trigger the McCarthy trade. Harbaugh said the quarterback search began after Dart went down one week earlier.

'Our design is to win the next game,' Harbaugh said when asked about the future quarterback picture.

That approach helps explain why New York was willing to spend a future fifth-round pick on another quarterback. McCarthy gives the Giants a 23-year-old former top-10 selection to evaluate while Winston continues to lead the offence.

The move still carries uncertainty. McCarthy has not established himself as a long-term NFL starter, and his 2025 numbers included more interceptions than touchdown passes.
