4-star DL Tomuhini Topui decommits from Oregon, USC trending as new favorite
Four-star Santa Ana (Calif.) Mater Dei defensive lineman Tomuhini Topui from has decommitted Oregon, according to On3’s Hayes Fawcett.
Topui had been committed to the Ducks since October 2024, when he chose them over USC, Georgia, Texas A&M, Auburn and dozens of other offers.
Immediately after his decommitment, On3’s Steve Wiltfong and Chad Simmons both logged expert predictions in favor of the Trojans as the new favorite to land him.
Despite his pledge back in the fall, the Trojans have continued to push hard for him and hosted him on campus in L.A. multiple times.
Those efforts, plus the connection he has built with multiple members of the coaching staff, looking to be paying off in their favor.
“Growing up, being from LA that’s always been my dream school and stuff,” he told ScoopDuck earlier this month. “Especially now with Coach Nua, he’s always been talking to me. It’s down the street, so I might as well just take a couple visits there, see what they’re talking about. Every time I go down there it’s great vibes, picking up family vibes.
