Again, the triple option is much more difficult to stop than people realize.  They allowed an alarming amount of points but they also scored 63 points on offense with just 17 minutes of possession.  That's an incredible 3.7 points per minute.  Wake Forest continues rolling their way towards an improbable ACC title.
It takes a special kind of defense to allow a triple-option team in Army to THROW 3 TD's on you + the other 5 rushing TD's...but having an offense that can throw 5 TD's and rush for 4 helps out.
