Third Down Woes Nearly Cost GA Tech

SB Nation's From the Rumble Seat breaks down the game, and is particularly concerned about the way GA Tech handled third down play-calling:

Here are the third down play selections we had and the yardage to gain a first down: incomplete pass (13), -3 yard rush (4), incomplete pass (6), incomplete pass (5), incomplete pass (8), 0 yard rush (4), 5 yard rush (6), 1 yard rush (3), incomplete pass (9), 24 yard pass (9), 4 yard rush (1), 2 yard rush (9), 39 yard pass (11), 4 yard rush (5). So play calling on third down included 7 passes (50% of 3rd downs). We only converted 3 of them. I'm not the coach and I'm not complaining about a win. I'm just wondering why we passed 50% of the time on third down when we passed only 23% of the time all game. Our passing game is a huge liability at this point, in my opinion.
