Key metric: NFL Coaching Stability

Let me tell you something - this is a GAME-CHANGING play in the NFL coaching world! Mike Tomlin, a true franchise quarterback in the coaching realm, is hanging up his cleats after an MVP-caliber 19-season run. This isn't just a substitution, folks, it's like losing your star player right before the playoffs! The Steelers, known for their coaching dynasty, are now facing a fourth-and-long situation as they search for their next field general. Tomlin's ironman streak of never having a losing season is like pitching a perfect game for nearly two decades - it's UNHEARD OF in today's high-pressure league. Now, the Steelers front office needs to step up to the plate and knock it out of the park with their next hire. This is a pivotal moment that could make or break their championship aspirations for years to come. The pressure is ON, and the clock is ticking!
