People refer back to that 5 game winning streak under Martz as Cutler's best streak with the Bears. In actuality, what happened at that time, was we were horrible the game before that, I think it was against Buffalo
I think it was the game before Buffalo as they were coming off a bye week that sunday(I remember cause I went to that game).
The Buffalo game was the game in the 2010 season after the bye where Martz dialed down the 7-step drops, ran the ball more and played more conservative, balanced football. They looked better after that, with the exception of the two GB games (season finale and NFCC).
The 5 game win streak in 2011 came after they started playing better, after another Packers loss in week 3, the beat Carolina in week 4. Then week 5 was that Monday night game in Detroit where the OL was getting annihilated but Cutler played pretty well.
So really he had 6 straight games where he played well, because after that Lions game was the blowout win over the Vikings at home which started the 5-game winning streak. That was followed by the London game against the Bucs where Forte had that cool TD run where the Bucs defenders ran into each other on his juke. Then they beat the Eagles with Vick, then that great home win over the Lions where the defense got a bunch of turnovers and Briggs jacked up Megatron. Then the Chargers game where they won but Cutler got injured.
