USC’s push for Tustin receiver Hayden Koo is getting a little louder, and the four-star prospect is clearly feeling it.
Koo, a 2028 receiver from Tustin, Calif., has been one of the summer’s standout recruits no matter which class you want to compare him against. His showing at The Opening Finals late last month at Nike Headquarters in Oregon only added to that buzz. The event brought together 120 of the country’s top prospects from the 2027 and 2028 classes, and Koo called it a “once in a lifetime” opportunity.
His recruiting board has filled out fast over the past few months. USC, Michigan, Ohio State, Oregon and BYU have all offered, while Stanford and UCLA remain heavily involved as well.
“It's been great, a real blessing for sure,” Koo said. “It's really just showing my hard work and dedication over the years.
Right now, I'm really just trying to train, get ready for the season. The camps really got me ready and getting coaching from top guys and competing on a high level.”
Even with the attention building, Koo said he’s not losing sight of how quickly things can change.
“I think there's a lot of schools that I didn't expect to come on the rise for sure, and so it's super cool just to hear from a whole bunch of coaches,” Koo said.
USC has become a major player in his recruitment, and two Trojans commits in the 2027 class are helping keep the pressure on: five-star athlete Honor Fa’alave-Johnson and four-star receiver Quentin Hale.
“I have a great relationship with Q. I played with him a couple times with Trillion Boys, and then also at The Opening," Koo said. "It was great to be teammates with Q, just kind of talk with Q, and then Honor, playing against them, and also seeing them around, super cool.”
That connection showed up again this weekend when Koo lined up against Fa’alave-Johnson in the first game of the Battle of the Beach 7v7 tournament. The USC commit’s message was simple: “Fight On.”
Koo also spent time with USC inside receivers/tight ends coach Chad Savage at the Trojans’ invite-only prospect camp last month, where the No. 159 overall prospect, No. 23 receiver and No. 10 recruit in California landed his USC offer. That relationship has been building, too.
The Trojans have made a habit of loading up on California talent over the last two recruiting cycles, and Koo has noticed. USC wants that trend to keep rolling in the 2028 class, and the Orange County receiver is one of the priorities.
With the 2026 season getting closer, Koo is beginning to sort out his fall visit plans. Nothing is locked in yet, but he did point to USC’s late-September matchup with Oregon as one home game at the Coliseum he wants to see.
Stanford, UCLA, Northwestern, Michigan, Oregon and BYU are also schools Koo said he may visit during the season.

USC Could Catch Wisconsin In A Coach's Most Desperate Game
Lincoln Rileys seat at USC still draws plenty of attention, but the more fragile situation in this matchup belongs to Wisconsin and Luke Fickell. The Badgers have gone through two straight down years, and after the rough 2025 season, plenty of observers expected a change. Instead, Wisconsin is trying to buy time and stability, while USC enters the game with the kind of expectation that usually comes with being the more talented team on paper.
For the Trojans, that makes this one feel less like a toss-up and more like a chance to keep a struggling opponent from finding any footing. USC is expected to handle Wisconsin, and anything short of that would raise immediate questions about where this program is headed under Riley. For Fickell, the pressure is even more immediate, because the margin for error in Madison has already shrunk to the point where every game now feels like part of a final exam. [Read more 🡒]
USC Ace Mason Edwards Just Delivered A Huge Draft Moment
Mason Edwards rise at USC ended with the kind of draft moment that confirms just how far his college career came. After missing most of the 2025 season because of injury, the former Trojans pitcher returned in 2026 and turned himself into one of the most dominant arms in the country, finishing with 8 wins, a 2.07 ERA and 15.9 strikeouts per nine innings while anchoring USCs staff.
The season also brought national recognition, with Edwards emerging as a finalist for the National Pitcher of the Year Award and earning Baseball Americas pitcher of the year honor. His performance made him the highest-drafted USC player since Brad Boxberger in 2009, and now he heads into the Athletics minor league system with the sort of momentum that can change the early shape of a pro career.
