Antonio Ramiro Romo (born April 21, 1980) is an American football television analyst and former quarterback who played 14 seasons with the Dallas Cowboys of the National Football League (NFL). He played college football for Eastern Illinois University, where he won the Walter Payton Award in 2002, and led the Panthers to an Ohio Valley Conference championship in 2001. He signed as an undrafted free agent with the Cowboys in 2003. Beginning his career as a holder, Romo became the Cowboys' starting quarterback during the 2006 season.

On September 7, 2008, Romo led the Cowboys to a 28-10 win over the Cleveland Browns in their season opener. Romo completed 24 of his 32 passes for a total of 320 yards and one touchdown. After the game, Romo required 13 stitches for a large gash on his chin that occurred during the third quarter when linebacker Willie McGinest hit him in the chin with his helmet. The NFL fined McGinest $7,500 for the hit.  On September 15, Romo led the Dallas Cowboys to a 41-37 win against the Philadelphia Eagles in the second game of the 2008 season. Romo completed 21 of his 30 passes for a total of 312 yards and three touchdowns. The 54 combined points scored by the Cowboys and Eagles in the first half were the second most points scored in a half during a Monday Night Football game.  Romo and the Cowboys won their third straight before losing to the Washington Redskins, falling to 3-1. Following a win against the Cincinnati Bengals, Romo was injured in a loss to the Arizona Cardinals. The Cowboys, under Brad Johnson, went 1-2 the next three games, falling to the St. Louis Rams, beating the Tampa Bay Buccaneers, and losing to the New York Giants.  In what became a de facto third playoff game for Romo shortly prior to its start, on December 28, Romo and the Cowboys failed to compete against the Philadelphia Eagles in a 44-6 loss. Romo committed three turnovers in the game and went 21/39 for 183 yards and no touchdowns. The loss dropped Romo's combined record in December to 5-8 and again raised questions about his performance in games of consequence.Answer this question using a quote from the following article:
