You guys haven't watched much of TCU if you think they won with their D last year.
You're right, it wasn't their 18th ranked defense...it was their 5th ranked offense.
TCU also ran an uptempo offense with 80 plays per game, compared to our embarrassing 66. They ran 70 plays per game in 2013, Patterson realized that he needed to change his offensive philosophy to maximize the teams potential. Golden will tell you the team was just closer though.
Patterson don't give a **** about where his D ranks, he cares about Ws.
