DU: The defense will keep the Longhorns streak of winning 10 games for the past nine seasons alive. How many more they win is up to Gilbert. If he plays well, Texas could go undefeated. The defense won’t be able to beat teams like Texas Tech, Oklahoma, Nebraska and Texas A&M by itself. If he plays poorly in those games, the defense will need to make a couple big plays or force some timely turnovers to win.
