I'm sure some have already been mentioned, but aside from the 4 super bowls-
04- steelers game against 3rd stringers, first bills game I ever went to
05 - snf against the patriots
06 - blowing an 11 point lead against the titans to knock us out of playoff contention
07 - mnf against dallas
08 - mnf against Cleveland
09 - mnf against the Patriots, mckelvins infamous fumble
10 - the entire season
11 - 5-2 to 6-10, enough said
12 - I can't even remember this forgettable season
13 - Ej manuel
14 - Oakland
I'll stop here. No need to relive the last few years
