I couldn’t find any credible, up-to-date reports—breaking or otherwise—indicating that Mike Sullivan, the head coach of the New York Rangers, has submitted a resignation letter. Instead, what’s verifiable and recent is that:
After a mutual parting with the Pittsburgh Penguins in late April 2025, Mike Sullivan was swiftly hired as head coach of the New York Rangers on May 2, 2025—becoming the 38th coach in franchise history
He signed a five‑year deal worth a reported $32.5 million (about $6.5 million annually), making it the richest coaching contract in NHL history
Sullivan replaces Peter Laviolette, who was fired after the Rangers missed the playoffs, finishing the 2024–25 season with a 39‑36‑7 record
There’s no evidence that Sullivan has resigned or even considered stepping down since taking the job.
Championship pedigree: Coached the Pittsburgh Penguins to Stanley Cup victories in 2015–16 and 2016–17, and holds the record for most wins in franchise history (Strong ties to the Rangers and USA Hockey: Served as an assistant coach in New York from 2009–2013, coached Chris Drury internationally and professionally, and is set to lead USA at the 2026 Winter Olympics
High expectations: Known for emphasizing team cohesion, consistent work ethic, and tighter defensive structure—something he underscored in recent interviews p with other hockey coaching news. But as of today (June 25, 2025), Sullivan is firmly entrenched as the Rangers’ head coach—no resignation, no drama.
If you’re seeing “breaking” rumors claiming otherwise, they’re likely false or based on confusion. Want me to keep an eye out for any major developments or clarify media coverage further?
