The Buffalo Bills finished 4-0 in the preseason for the first time in franchise history, beating the Minnesota Vikings 27-23 on Thursday night at New Era Field.

Buffalo last went 3-0 in the preseason in 1966. That team went 9-4-1 before losing to Kansas City in the AFL championship.

"I know it’s preseason but to go 4-0, for the first time in franchise history, that says something about our guys and the way they battled and the coaches and the staff," Bills coach Sean McDermott said. "It is preseason, I get that, but it’s good to go and do it at home as well with this type of win at the end."

The Bills are among eight teams that entered their respective preseason finales unbeaten (that group includes the New England Patriots).

But what would a 4-0 preseason mean? Well, not necessarily much.

According to BNBlitz's Nick Veronica, since the NFL realigned divisions in 2002, 36 teams have gone undefeated in the preseason.
