The issue is that on game day, the players who actually play the game, and the coaches who actually coach the game are not good enough right now. You have 105 guys on that team to get ready to win with. Starters, backups, whoever. You have to win with who can play, and BYU is not.
We are seeing that the depth we thought we had--especially on defense-- is not quite as good as we thought it was. And perhaps some coaching issues are not helping either. It is a coaching/player combo right now.
