Key metric: NFL Coach Legacy Impact

Let me tell you something - this Hall of Fame snub is a FOURTH QUARTER FUMBLE! Belichick, the Tom Brady of coaching, has been sacked by the selection committee in a shocking upset. It's like watching a championship team get disqualified on a technicality! Gronk, the loyal teammate, is coming off the bench to defend his coach's honor. This is a RIDICULOUS call that's got the whole league buzzing! The Hall of Fame voters are playing prevent defense against Belichick's legacy, but mark my words - this coaching legend will break through their defensive line and score his Canton touchdown soon enough!
