You obviously didn't "chart" the game good enough. Right before the 3rd and 15 big reverse by quarles, DT lost 7 or 8 yards out of wildcat. Not to mention after the first down (with momentum), we went wildcat two plays and gained 3 yards. Its a drive killer.
My mistake, we still averaged over 4 YPP out of the Wildcat. The 7 yard loss you used though is a poor example of the Wildcat being ineffective b/c it was a poor snap as much as anything that caused the problem on that play. And you are correct, we did run 2 more plays out of it for a 2 yard gain (lead) and then a 1 yard gain (option), but had Thomas pitched the ball we gain minimum 5 yards on that one. So perhaps you could argue that we used it too much on the first drive.
But again, it does not make it a negative offense, especially when we mixed it in on the 2 TD drives and gained 9 and then 13 yards respectively out of it.
