Passage: Colby Carthel, who had played linebacker for the Angelo State Rams from 1996 to 1999, was named the A&MCommerce head coach in January 2013, following the resignation of Morriss in November 2012. During the 2013 season, the team upset NCAA Division I FCS team Houston Baptist, 5521. In December 2013, three Lions football players were named to the All-Super Region Four team: defensive end Charles Tuaau (first team), as well as wide receiver Vernon Johnson and defensive end Tevin Moore (second team). Darvin Peterson and Tuaau were the fifth and sixth Lions to be named to the AFCA All-America first team when they accomplished the feat in 2006 and 2013, respectively. During the 2014 season, the Lions set a Division II record for total offense when they accumulated 986 yards against East Texas Baptist in a 9820 win. Lions football players of this era who went on to play in the National Football League include Cedric Bonner, who signed with the Atlanta Falcons in 2005, and 2012 Lone Star Conference (LSC) Linebacker of the Year Danny Mason, who signed with the Denver Broncos in 2015.
