BYU's record is currently 7-4. They are 6-1 at home, 0-3 on the road, and 1-0 in neutral-site games.
They are currently shooting 28.8% from 3. That is definitely their Achille's heel. They clearly play better at home than on the road. There is really no excuse for two of their road losses. Against Illinois State, BYU, somehow, found a way to snatch defeat from the jaws of victory. In that game they shot only 21.4% from 3 (6/28). And giving up 113 points to Weber State in Ogden is, frankly, inexcusable. They also lost to top-ten Nevada in their first game by 16 points which was much closer than that for most of the game. BYU shot 19.4% from 3 in that game.
BYU shot 28.6% (8/28) from 3 in a home loss to Houston. Their best game, by far, in terms of 3-point shooting was against Utah State. In that game BYU shot 45.8%. Chances are, if they shot 28% from 3 in that game they likely would have lost.
In order to be successful BYU MUST shoot better and more consistently from 3. If they were shooting 35% on the season instead of 28.8%, they would likely have a couple more wins than they do now. That's typically just a couple more makes a game, but it makes a significant difference.
