"USC just offered me," said Stills.
Stills was thrilled to receive the offer from the Trojans.
"I'm real excited and appreciative of this offer," said Stills. "I have been working real hard and it continuously pays off. I am blessed and am thankful for everything that's come and coming my way."
However, he's not ready to make a decision.
"I'm not deciding for a while," said Stills. "I'm going to take all of my visits."
Stills said that USC coaches had been by the La Costa Canyon campus on Monday and made the offer as a result.
A Scout 300 member, Stills is a four-star prospect by Scout.com.
In March, he was named to the All-Camp team at the Badger/Scout 7on7 Tournament and will be at the Scout.com Combine later this month in Los Angeles.
Stills helped lead La Costa Canyon to the CIF-San Diego Section D-I championship, leading all of San Diego in receiving yards with 1,274 on 64 receptions and scored 16 touchdowns. He was named First Team All-State Underclass by GoldenStatePreps.com.
Kenny Stills makes the catch.
