Key metric: NFL Coaching Legacy

Let me tell you something - this Hall of Fame snub is RIDICULOUS! Bill Belichick, the Tom Brady of coaching, just got sacked on what should've been a slam dunk play! We're talking about a guy who's been to the Super Bowl more times than some franchises have won playoff games! This is like denying Michael Jordan first-ballot entry because he played baseball for a while. The Hall of Fame committee dropped the ball harder than the Falcons in Super Bowl LI! Belichick's coaching record is nothing short of legendary - we're talking about a dynasty-builder who's been playing 4D chess while other coaches are still learning checkers. Patrick Mahomes stepping up to defend Belichick shows the kind of cross-team respect you only see for the true GOATs of the game. This isn't just a fumble by the Hall of Fame, it's a full-on pick-six against their own credibility!
