Key metric: NFL Head Coach Hiring Success Rate

Let me tell you something - this coaching carousel is SPINNING OUT OF CONTROL! We've got a QUARTER of the league looking for new head coaches, and it's like the NFL draft of sideline generals! The Baltimore Ravens just threw a Hail Mary by cutting ties with John Harbaugh, but let me tell you, that vacancy is now the Tom Brady of coaching jobs - EVERYONE wants a piece of it! Meanwhile, the Miami Dolphins are playing defense against their own reputation, with league insiders treating that gig like it's a fumble nobody wants to dive on. This is a high-stakes game of musical chairs, folks, and these coaches are sprinting to grab the best seats before the whistle blows!
