No, but they were a huge part of it
It was a team loss.
The offense had too many 3 and outs, which tired out the defense. Of course if the defense could stop the Falcons they could get off of the field. With this sad, they couldn't get the stop they needed to win the game. Partly because of injuries to the LB's/Secondary. I could see a trade at the deadline for a LB and an Edge.
