My worst game might be against the Jets in 1989 it ranks as the 5th coldest game in Bills history.
They won in a landslide though.
My 78 Impala winter beaters heat was not working so we froze going there and back home.
While digging out my seat some woman comes up behind me and gets showered in snow then yells at me " what are you a Canadian Beaver" I relied NO but I like to eat it..... she wasn't impressed
The real worst part is I was at 7 of the 10

5. Dec. 23rd 1989 – at N.Y. Jets, 16 degrees, wind chill of minus-11The Bills felt right at home in the blustery Meadowlands as Buffalo's offense had it in cruise control and the defense had the hapless Jets stymied from start to finish.
Buffalo's defense held the Jets to just 54 yards rushing with Cornelius Bennett and Bruce Smith both logging a pair of sacks. Bennett also had an interception.
Fullback Larry Kinnebrew had a big day with 91 yards rushing and a touchdown, with Thurman Thomas and Kenny Davis combining for another 106 rushing yards and two scores en route to a 37-0 whitewash of the Jets.
With the win Buffalo clinched the AFC East title.
