At the time, he was committing to interim coach Ed Orgeron.
Much has changed in the Los Angeles college football scape since then.
For starters, Talamaivao and his Centennial Huskies are now CIF-SS Inland Division Champions, and his future coach at USC is now Steve Sarkisian.
"I think it was the best move for ‘SC," Talamaivao explained on Friday night, after his team defeated Murietta (Calif.) Vista Murrieta. "I have a lot of respect for Coach [Ed Orgeron], but Coach Sark, he is a real good dude."
Talamaivao, a four-star recruit, says he has a long-standing relationship with the former Washington coach who recruited him to be a Husky. "[Sarkisian] revived Washington, from 0-12 when he got there and got them to [four] consecutive bowl games."
Sarkisian brings with him from Washington running backs coach Johnny Nansen.
Nansen is the uncle of Talamaivao. He was on the sideline of the game recruiting for the Trojans.
The Trojans have yet to name a new offensive line coach, but Talamaivao says despite who the hire will be, he's "excited to get started".
As for who else is still involved in Talamaivao's recruitment? He says he's all USC.
Once thought to be considering UCLA, Talamaivao said, "To be honest, they haven't really kept up with me as far as recruiting, so I'm set on USC."
Centennial will face off against Bellflower (Calif.) St. John Bosco in the CIF-SS Open Division on Saturday at Cerritos College.
