Question: In 2015, Baker Mayfield won the Oklahoma starting quarterback position over which future Atlanta Falcons quarterback?

<P0-S0> Tyrod Di'allo Taylor (born August 3, 1989) is an American football quarterback for the Buffalo Bills of the National Football League (NFL). <P0-S1>  He was the starting quarterback for the Virginia Tech Hokies football team from the start of the 2008 college football season through the 2011 Orange Bowl, the final game of the 2010 college football season for Virginia Tech. <P0-S2>  He was drafted by the Baltimore Ravens in the sixth round of the 2011 NFL Draft and served as the backup to starting quarterback Joe Flacco, including during the Ravens' Super Bowl XLVII victory over the San Francisco 49ers. <P0-S3>  Signed by Buffalo as a free agent in 2015, Taylor was named the starting quarterback for the Bills at the beginning of the 2015 NFL season. <SEP> <P1-S0> The 2015 Buffalo Bills season was the franchise’s 56th overall season as a football team, 46th in the National Football League, third under leadership of general manager Doug Whaley and first under new head coach Rex Ryan, who signed a five-year, $27.5 million contract on January 12, 2015 after having previously spent the past six seasons coaching the division-rival New York Jets, leading them to two straight AFC Championship games in 2009 and 2010, becoming the franchise’s 18th head coach and the fifth in the past seven years in the process. <P1-S1>  Ryan replaced Doug Marrone, who opted out of his contract on December 31, 2014 to take advantage of a contract loophole, fearing the Pegulas were going to fire him, hence the reason the Bills entered the 2015 season looking for a new head coach. <P1-S2>  Despite the bold prediction made by Ryan at his introductory press conference, where he stated, “I’m not going to let our fans down. <P1-S3>  I am not going to do that. <P1-S4>  I know it’s been 15 years since the Bills made the playoffs. <P1-S5>  Well, get ready, man, we’re going. <P1-S6>  We are going,” the Bills were unable to make the playoffs in their first season with Ryan as head coach, finishing with a record of 8-8 (the team’s first since 2002), making it the 16th straight season without a playoff appearance, which became the longest active in major professional sports after Major League Baseball’s Toronto Blue Jays broke their 22-year playoff drought on September 25, 2015. <P1-S7>  It was also the first full season under the ownership of Terry and Kim Pegula (whom also own the Buffalo Sabres), having purchased the Bills partway through 2014 after the death of longtime owner Ralph Wilson in March at the age of 95. <P1-S8>  The Bills began their season with an open competition for the starting quarterback position after Kyle Orton, the starter for most of the 2014 campaign, retired during the offseason, so the team acquired free agent Tyrod Taylor, a former backup quarterback of the Baltimore Ravens, who won the competition over incumbent second-string quarterback EJ Manuel and trade acquisition Matt Cassel, the latter of whom the team later traded along with a seventh-round pick in 2017 to the Dallas Cowboys, in exchange for a fifth-round draft pick in 2017. <SEP> <P2-S0> Baker Reagan Mayfield (born April 14, 1995) is a college American football quarterback for the Oklahoma Sooners. <P2-S1>  Mayfield began his college football career as a walk-on player for the Texas Tech Red Raiders. <P2-S2>  He is notable for being the first walk-on true freshman quarterback to start a season opener at a BCS school. <P2-S3>  Mayfield transferred from Texas Tech to Oklahoma following alleged scholarship issues and a lack of communication with coaches. <P2-S4>  After sitting out the 2014 season due to NCAA transfer rules, Mayfield won the starting quarterback job in 2015 over Cody Thomas and incumbent starter Trevor Knight. <SEP> <P3-S0>  He played college football for the Oklahoma Sooners and Texas A&M Aggies. <P3-S1>  After leading Oklahoma to an 8–5 record in the 2014 season, he lost the starting job in an open quarterback competition to Texas Tech transfer Baker Mayfield prior to the 2015 season. <P3-S2> Trevor Knight (born October 3, 1993) is an American football quarterback for the Atlanta Falcons of the National Football League (NFL). <P3-S3>  On January 4, 2016, it was announced that Knight would transfer to Texas A&M University.
