Offensive line is a tricky position at USC. We don't notice when the times are good, like when Matt Kalil and Khaled Holmes were anchoring the line a few years back. When things go wrong, however (as Aundrey Walker can attest),the fingers go straight to the big guys. This year, the line is one of USC's biggest strengths. It has the nation's top-ranked guard along with another guard and center ranked in the top five at their spots, as well as two raw, but rising tackles who could anchor the line down the road if they bulk up. 

Damien Mama, Offensive Guard

Star Rating (Rivals/Scout/247 Sports): 4/5/4

Pronounced 'Muh-maw', he is one of the jewels of Steve Sarkisian's first recruiting class, and one of USC's "Big 3" targets that made their choice on National Signing Day. At 6-foot-5 and 360 pounds, he's near immovable in pass protection and can flat out run over defenders when run blocking. He's a tackle at St. John Bosco H.S., but can move to guard, where he'll pancake defender after defender. He's no speedster (shocking, I know), but he's an elite get and considering that you can't teach his combination of size and strength, could be Sarkisian's first recruit to see significant playing time in Year 1. 

Viane Talamaivao, Offensive Guard

Star Rating: 4/4/4

Good friends with Mama, Talamaivao committed in November shortly after decommitting from Alabama, and has been a Trojan recruiter ever since. He's 6-foot-2 and 330 pounds, but is quick off the snap for his size and can push his defender downfield. He's a bit raw with his form all around, and could get beat by shifty pass rushers early, but there's no reason he can't see time in 2014 if injuries or poor play necessitate it. 

Toa Lobendahn, Offensive Guard/Center 

Star Rating: 4/4/4

Another Southern California product, Lobendahn can play around the offensive line and is a pass-blocking savant. He's already at USC, one of the Trojans' five spring enrollees, and gets to spend the spring preparing to possibly replace Marcus Martin as the Trojans' center. That time will probably happen in 2015 rather than 2014 though, as Lobendahn is raw all around and needs to fix some kinks in his technique before he becomes a key contributor.

Chris Brown, Offensive Tackle

Star Rating: 4/4/4

What do you know, another Southern Californian! No, not the R&B singer. At 6-foot-6 and 285 pounds, Brown is a late riser from Loyola H.S. that has the frame to be a dominant left tackle. He's a well-balanced lineman, able to spring off the line as well as push back defenders in run blocking. Like Chad Wheeler before him, who put on weight to become the starting left tackle as a redshirt freshman, Brown has all the tools to become an impact linemen. How he adjusts to the college game though, has yet to be seen.

Jordan Austin, Offensive Tackle

Star Rating: 3/3/3

The most raw of the offensive line recruits, Austin is athletic but needs to become more consistent and work on his down blocking. He needs to gain weight to play at USC, but if he does, we could see him down the line using his athleticism to shut down rushers on both sides of him. He's also here already, which means an extra year working with offensive line coach Tim Drevno.
