Overview
- Mike Tomlin stepped down Tuesday after 19 seasons with the Steelers, reshaping tenure rankings across major U.S. leagues.
- Erik Spoelstra, now in his 18th season since taking over the Miami Heat in 2008, leads all active coaches across the NBA, NFL, NHL and MLB.
- Spoelstra said Tomlin’s exit “really bummed me out” and argued that coaches are too rarely given time to work through difficult stretches.
- Coverage also notes John Harbaugh was dismissed this season after 18 years with the Ravens, underscoring league-wide turnover.
- The next-longest current runs include Andy Reid with the Chiefs and Jon Cooper with the Lightning, both since 2013, with Spoelstra five seasons ahead of Cooper.
