Is PC the real problem with offense?

Sean is a great offensive coach, but there was still plenty of “why is/isn’t this guy on the field for (insert crucial situation)?!” when he was here.

The catch is that it only gets noticed when it doesn’t work, similar to our team averaging more YPC with Bowden on the field earlier in the season even though the consensus was that we were tipping our hand.
How many games did we run the screen 15 times to gain a total of 15 yards...
