Question: Who was the winning coach in the 2009 Big 12 Championship Game?

<P0-S0>  The team was coached by Mack Brown. <P0-S1>  Texas played their home games in Darrell K Royal–Texas Memorial Stadium. <P0-S2> The 2009 Texas Longhorn football team (variously "Texas" or "UT" or the "Horns") represented the University of Texas at Austin in the 2009 NCAA Division I FBS football season. <SEP> <P1-S0> The 2009 Nebraska Cornhuskers football team represented the University of Nebraska–Lincoln in the 2009 NCAA Division I FBS football season. <P1-S1>  The Cornhuskers played their home games at Memorial Stadium in Lincoln, Nebraska and were led by head coach Bo Pelini. <P1-S2>  The Cornhuskers finished the season 10–4, 6–3 in Big 12 and were Big 12 North Division champions and represented the division in the Big 12 Championship Game, where they lost to Texas 13–12. <P1-S3>  Nebraska was invited to the Holiday Bowl, where they defeated Arizona 33–0. <SEP> <P2-S0> The 2005 Colorado Buffaloes football team represented the University of Colorado at Boulder in the 2005 NCAA Division I-A football season. <P2-S1>  The previous year's team won the Big 12 North Conference. <P2-S2>  That marked the third Big 12 North championship for the Buffaloes in four years. <P2-S3>  The team had expectations to improve on their winning and appeared to be on the right track with a 7–2 record to begin the season. <P2-S4>  But in the end, head coach Gary Barnett had his contract bought out and Colorado suffered four straight losses including an embarrassing 70–3 loss to Texas in the Big 12 Championship Game. <P2-S5>  They finished the season 7–6. <P2-S6>  In the 2005 Champs Sports Bowl against Clemson, Mike Hankwitz acted as interim head coach, even though Dan Hawkins had been hired as the new head coach. <P2-S7>  Hawkins coached his final game with Boise State in the game the day after Colorado played. <SEP> <P3-S0> The 2009 SEC Championship Game was played on December 5, 2009, in the Georgia Dome in Atlanta, Georgia, to determine the 2009 football champion of the Southeastern Conference (SEC). <P3-S1>  The game featured the Florida Gators and the Alabama Crimson Tide. <P3-S2>  The Crimson Tide was the designated "home team"; this home team, chosen on an alternating basis, was 2–4 in SEC Championship Games. <P3-S3>  The winner was all but assured to go on to play for a National Championship, in a likely matchup with the Texas Longhorns provided Texas won in the Big 12 Championship Game versus the north division champion Nebraska Cornhuskers. <P3-S4>  Entering the 2009 contest, the SEC East was 11–6 in SEC Championship games, with the Florida Gators accounting for seven of the eleven victories. <P3-S5>  Before the 2009 game, Alabama represented the SEC West six times in the conference championship game, compiling a 2–4 record, and had faced the Gators in all six of their previous SEC Championship game appearances. <P3-S6>  This was the first and so far the only time any conference championship game had featured two undefeated teams and was also the first time an AP Poll No. 1 played a No. 2 outside of the BCS Championship Game since the top-ranked Ohio State beat the second-ranked Michigan during the 2006 regular season.
