TCU, BYU turning red zone into green zone

It isn't just defense that has Mountain West foes TCU and BYU among the top teams in the country. Both have impressive offensive numbers this season: BYU is No. 7 in the nation in total offense at 469 yards per game; TCU is No. 22 at 431 yards.

But those stats don't mean much if you don't score when you are inside the opponent's 20-yard line. Both teams do that. BYU is 31-of-33 in the red zone, scoring 94 percent of the time. The Horned Frogs are 25-of-29 in the red zone, an 86.2 percent success rate, second only to BYU in the MWC.

Which defense does better in the red zone? That's where TCU has an advantage this season. The Horned Frogs are tied for 25th in the nation in red zone defense (holding opponents scoreless in the red zone 25 percent of the time). BYU is tied for 61st.

That will be an interesting stat to follow Saturday.
