The last time the New England Patriots played a game without Bill Belichick as their head coach, it was right after Y2K.
On Jan. 2, 2000, the Patriots beat the Baltimore Ravens, but Pete Carroll was fired as head coach anyway. The day before, Tom Brady played his final college game. There are many ways to illustrate how life has changed since then, but in the Patriots' world, this is what matters: They went from one of the NFL's forgettable franchises to winning 17 AFC East titles, nine AFC championships and six Super Bowls with Belichick.
