Moala originally signed with the
University of Southern California in 2003, but did not qualify for admission. He attended
Cypress College for one year, but did not play football there, before transferring into USC. During his first year at USC in
2004 he was
redshirted. In
2005 he started two games for the Trojans recording eight
tackles. During his sophomore season in
2006, Moala pushed for and eventually won the starting spot, starting the last seven games and received All-
Pac-10 honorable mention. In the off-season and into the beginning of the 2008 season, Moala suffered from
back spasms that limited his time in practices; he did not register a tackle during the 52–7 rout against the Trojans' first opponent,
Virginia, which ran a
spread offense that did not emphasize the run. Moala showed marked improvements in the following game against
Ohio State, where he made a sack and contributed to a defensive line that had tackles for losses, including five sacks. Moala had a strong game against
Arizona State, where he made three tackles, recovered a fumble, and blocked two third-quarter
field goal attempts, tying the
NCAA record for blocked field goals in a quarter. ==Professional career==
