Let me tell you something - this story is HUGE! The New York Giants just pulled off a MAJOR LEAGUE PLAY by signing John Harbaugh as their new head coach! This is like drafting a Hall of Famer in the first round, folks! Harbaugh's got that championship DNA, and with Trump cheering from the sidelines, this could be the GAME-CHANGING MOVE the Giants need to get back to the Super Bowl! I'm telling you right now, the rest of the NFC East better watch out because the Giants are suiting up for a FOURTH QUARTER COMEBACK that could shake up the whole division!
