A couple things, but Defense has it's finger prints on most of the reasons. Here is one most won't realize
We had 18 & 10 TO last 2 games, and our Opponent only scored 10 Pts off the TOs. So we are getting back not giving up easy points when the TO isn't a deadball TO (like a bad pass out of bounds)
Last night we made UK pay. 24-7 edge. We scored the 24 points off of their 15 TOs.
