BYU started 3-1 & then finished 4-5 the rest of the way. I'm not sure if that is improvement or playing better.
There worst losses were games 5, 6 & 8. They lost their only opportunities for good wins in the back half of the year although we can claim moral victories over Boise & Utah if you want.
SDSU, USU, Boise, USF, and Toledo all have more wins over the last three years than BYU and all should be respected as decent opponents, especially on the road.
