Stills started the visit at Fresno State on Friday.
"Fresno was cool and I have a great relationship with the coaches," said Stills. "But I don't know if it's really the place for me."
The next day, Stills was on to Berkeley, a visit that had him thoroughly impressed.
"I loved it there, absolutely loved it," said Stills. "I loved all the coaches and everything they have going. I spent most of my time with Coach (Kevin) Daft and Coach (Jeff) Tedford. Everything they have going there is big time. And they also know how to see their program even more big time."
Finally, Stills concluded his trip with a visit to Westwood to see UCLA.
"I liked it at UCLA," said Stills. "I could tell they want me bad there. Coach (Rick) Neuheisel was the coach I spent most of my time with when I was at UCLA and also Coach (Tim) Hundley. I like the campus and I was in awe of the scenery."
The weekend after earning MVP honors at the Los Angeles Scout.com Combine, Stills took it easy, but he has camp plans later this month.
"Probably before the end of July, I'll narrow it down some," said Stills.
Stills also got another scholarship offer this week, from Maryland. Other schools that have offered (besides his seven favorites) are Washington, Colorado, Boise State, Stanford, San Diego State and Arizona.
As a junior, 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.
