The Horned Frogs are dominating on defense like they have so often under Gary Patterson, who was their demanding defensive coordinator before becoming head coach nearly 14 years ago. While Patterson hired new co-offensive coordinators last offseason to install a spread scheme more like what was prevalent in the Big 12, there were no wholesale changes on the defensive side he still oversees. TCU is coming off a 56-0 win at SMU, which followed an opening stretch when the Frogs had a bye week after each of their first two games — including a 30-7 win over Minnesota, which last weekend won at Michigan. Over the past 14 seasons, including Patterson's last as defensive coordinator in 2000 before replacing former boss Dennis Franchione, TCU has finished as the national leader in total defense five times. In their first Big 12 season in 2012, the Frogs led the league allowing only 324 total yards a game, even with only one senior on the depth chart while facing five of the country's top-13 ranked offenses.
