The list of times Bill Belichick has been embarrassed in the playoffs is short.
The instance everyone will point to is a 2009 wild-card game against the Baltimore Ravens, when the New England Patriots trailed 24-0 in the first quarter. They lost that game 33-14. In 2012 they lost the AFC championship game to the Ravens by 15 points. Those were the only times Belichick's Patriots teams had lost by more than 10 in the playoffs.
A lot about Saturday night's 47-17 Buffalo Bills win was shocking.
