2015: The young but experienced Mama will battle for a starting role at offensive guard as a sophomore in 2015.
2014: Mama saw significant action at offensive guard as a first-year freshman in 2014, appearing in 12 games (all but Washington State). He started USC's first 2 games at right guard, then started against Notre Dame and Nebraska at left guard. Against Fresno State, he and Toa Lobendahn became just the second pair of USC first-year freshmen in the post-World War II era to start on the offensive line (Travis Claridge and Faaesea Mailo did so 3 times in 1996), but it was the first time that a Trojan first-year freshman o-line duo started an opener.
HIGH SCHOOL: He made 2013 USA Today All-USA first team, Parade All-American first team, Prep Star All-American Dream Team, Max Preps All-American first team, Student Sports All-American first team, ESPN 300, Cal-Hi Sports All-State first team, Max Preps All-State Division I first team, All-CIF Pac-5 Division, Los Angeles Times All-Area Lineman of the Year, Orange County Register Fab 15 first team, Long Beach Press-Telegram Dream Team and Wave Newspapers All-East Region as a senior offensive and defensive lineman at St. John Bosco High in Bellflower (Calif.). St. John Bosco won the 2013 CIF Pac-5 Division championship and CIF state championship Open Division bowl game.
He made the 2012 Cal-Hi Sports All-State Junior first team. Current Trojans Nico Falah, Malik Dorton and Reid Budrovich also prepped at St. John Bosco.
