What's a trap or sandwich game?
It's an easy game sandwiched between two difficult games. It's a game a team is favored to win, but because of a letdown from the previous week and the distraction of next week's important game, it becomes difficult to concentrate on the game, and strange things happen.
The letdown could come from using up too much energy in winning, or from the disappointment of losing.
These games have become famous for some of the greatest upsets in college football history.
In 2007 West Virginia beat a 9-2 UConn team and needed a win at home against a 4-7 Pittsburgh team to go the BCS Championship. The Mountaineers got upset 13-9 in what became one of the worst moments in West Virginia football history.
In 2006 USC just came off a 44-24 win over 10-2 Notre Dame. All they needed was win over a 6-6 UCLA and they'd go to the BCS championship. UCLA beat them 13-9 and broke an eight-game series losing streak.
This year there are a lot of good sandwich games. I have chosen 10 of the best.
