Here are some of my faves:
Loss v. cleveland on the road in 07 when we were 7-6 and in the playoff hunt.
The shellacking at the hands of Jets at home in '11 when were 5-2 going in (exposed the team as a fraud just like Chris Carter told us).
Loss on the road to the Dolphins in '08, blowing a second half lead (would have gone 6-1).
Loss at home to SF in '08
Loss on the road to the Bucs wk 2, 05 (maybe this Losman thing was not such a good idea)
Loss at home to Dolphins in 00 (maybe this Johnson thing was not such a good idea)
Shellacking at home on SNF (we were flexed in) to NE in 07 to end 4 gm win streak (NE scores TOUCHDOWNS on 7/7 possessions).
