Joe Flacco's turning point was actually his lowest point of the season.
In Week 15, Flacco had an interception that was returned 98 yards for a touchdown in the Ravens' 34-17 loss to the Broncos. The lasting image was Flacco laying face first in the turf after a desperation tackle.
Flacco has certainly picked himself off the ground, going on a hot streak since throwing that pass. He has averaged 15.7 yards per completion while throwing nine touchdowns and no interceptions. His passer rating since that interception is 110.9.
Flacco hasn't been picked off in his last 15 quarters of play, a span of 126 passes. His longest streak of not throwing an interception is 137 passes, which happened two seasons ago.
Asked if he thought that interception against Denver affected him for the rest of the season, Flacco said, "It affected me right there. I was pretty unhappy about it, and rather than possibly making the game 10-7, it was 17-0. I think I do a pretty good job of taking care of the ball on a consistent basis. Things like that happen, and you have to be willing to deal with it and come out and continue to play the way that you think you can. I think that’s all that has been happening.”
