text: In 2009, TCU again attained national prominence with its second undefeated regular season (12–0) and first since Dutch Meyer led the Frogs to perfection in 1938. They lost in the 2010 Tostitos Fiesta Bowl 17–10 to the Boise State Broncos, on January 4, 2010—their first major-bowl appearance since the 1959 Cotton Bowl. In the following year, the Horned Frogs capped their second consecutive perfect regular season with a win in their first Rose Bowl, a 21–19 victory over Big Ten co-champion Wisconsin on New Year's Day, 2011. This capped off only the second undefeated and untied season in school history. After going 11–2 and winning the Mountain West title again in 2011, the Horned Frogs played Louisiana Tech in the Poinsettia Bowl. TCU won 31–24 in a somewhat lackluster performance after narrowly (and somewhat controversially) missing their third BCS Bowl bid in a row. TCU finished 16th in the final BCS rankings, two slots below the cutoff for a non-AQ team to get a BCS bid. The win allowed Patterson to tie Meyer as the winningest coach in TCU history. On October 10, 2011, the TCU Board of Trustees approved an invitation to join the Big 12 Conference, and entered that conference on July 1, 2012. The move to the Big 12 was a return "home" in a sense for the Horned Frogs, as they renewed many of their in-state rivalries from the old Southwest Conference. Before the move to the Big 12, the Horned Frogs had been reckoned as one of the closest things to a major football power in a mid-major conference. Amon G. Carter Stadium, the Horned Frogs' home field since 1929, concluded large renovations prior to the 2012 season. It featured a new press box, suites, club seats and improved fan amenities in many areas—new and more comfortable seating, wider concourses, new and improved restrooms and concessions areas, handicapped-accessible accommodations, elevators and escalators to move patrons among levels, and new lighting. The stadium was used during the 2011 season while being renovated. The Horned Frogs played their first game in the renovated stadium on September 8, 2012, and routed Grambling 56–0. The win was also Patterson's 110th win with the Horned Frogs, making him the winningest coach in TCU history. TCU would finish their first regular season in the Big 12 at 7–5 before losing to Michigan State in the Buffalo Wild Wings Bowl 17–16.
