Bill B. has 290 wins in regular season, and 31 in the playoffs.
290+31 = 321 (Next win is…)
On September 11, 2022, Bill Belichick will start the Patriots 2022 season and he can pick up his 322nd win, the number of Skull and Bones (again, George W. Bush, of Skull and Bones, was president when 9/11 happened). And funny enough, he is facing the rookie Miami Dolphins coach who went to Yale, where Skull and Bones is located. And if Belichick does get the 322nd win, he will stay on 156 losses (911, 156th prime number).
He’s also on 254 regular season win, and 111 total losses with the Patriots, on 9/11. September 11 is the 254th day of the year, leaving 111 days remaining.
Bill Belichick = 254
