To me, "coming out flat" translates to being unable to move the ball at the beginning of the game, and possibly being unable to stop the other team's offense.
In this game, the first time we had the ball, we moved from the 25 to midfield before punting and changing field position. We then held UGA to a three and out, got the ball back and moved from our 19 to around the forty before AJ got sacked and fumbled. The defense rose up and got a sack, and GA missed a long FG. We moved the ball from our 33 down to the GA 44 before getting the delay of game penalty on the fake punt, punting, and backing them up to the 13. From there, GA drove it down the field and scored a TD after THEIR fake punt worked. I just don't think we played flat at the beginning of the game, and it certainly didn't compare to the A & M game.
