Despite the decision by Giants ownership to keep head coach Brian Daboll, it was inevitable that changes would occur within his coaching staff for the 2025 season. After a disappointing 3-14 record, adjustments were necessary.

The first alterations were made on Wednesday, as Daboll let go of defensive backs coach/defensive game coordinator Jerome Henderson and safeties coach Michael Treier, according to The Post.

Both Henderson and Treier had been inherited from previous defensive coordinators. When Shane Bowen joined the team last year following Wink Martindale’s departure, he had kept most of Martindale’s staff. Now, Bowen’s coaching staff is set to undergo significant changes.

Henderson a year ago interviewed for the defensive coordinator position that went to Bowen and then was promoted to the passing game coordinator role. He was considered to be a popular and productive assistant but the results this past season were not there with cornerback Deonte Banks, the 2023 first-round pick. Banks struggled with lapses in effort and Henderson called him out on it – something Daboll never did.

Henderson, 55, played defensive back in the NFL and came to the Giants in 2020 as part of Joe Judge’s staff. Treier had been with the Giants for five years.

Following the season, co-owner John Mara was critical of several aspects of the 2024 Giants and sounded especially frustrated with the defense, saying “I didn’t think our defense played very well this year at all” and “I’m tired of watching teams go up and down the field on us.”

Some took that to mean Bowen’s job security was tenuous but that is not the case.

Many Giants players struggled to adapt to Bowen’s defensive approach, which was a departure to Martindale’s blitz-heavy, more aggressive scheme. Cornerbacks who grew accustomed to playing man coverage for Martindale had to adjust to playing more zone under Bowen.

The Giants allowed 210.6 passing yards per game, the eighth-lowest total in the NFL, but much of that was opponents focusing on running against the Giants; their run defense was 27th in the league.
