UNLV took Brigham Young to the wire last week in a 42-35 loss. The Rebels also played close with Air Force and Colorado State.
Led by defensive end Jerry Hughes, TCU is No.2 in the country in total defense (218 yards per game) and scoring defense (10.8 points per game).
The Frogs have plenty of reasons to take UNLV seriously.
