Washington State became the latest school to offer Dreyer, doing so on Thursday.
During the spring, Dreyer visited Cal and UCLA.
"I took a day trip over to Cal and then during spring break, I went to UCLA," said Dreyer.
Dreyer had teammates sign with both the Bruins and Bears, and that's gotten him noticed by their respective staffs. Matt Dickerson signed with UCLA and Hamilton Anoai inked with the Bears.
"I've talked with each of them about the schools they're going to and got a great idea of what each school offers," said Dreyer.
Dreyer was at UCLA for a spring practice and got to spend time with offensive line coach Adrian Klemm and his area recruiter, Angus McClure.
"At UCLA, Coach Angus showed us around but I also got a chance to talk with Coach Klemm for a couple of minutes," said Dreyer. "He said they were interested and they would be checking me out and that they would like me to come to camp."
Dreyer made a quick drive over to Cal and got to see the Berkeley campus.
"The visit to Cal was nice," said Dreyer. "Growing up in the Bay Area, I've always followed them. They have a beautiful campus with brand new facilities that are nice. Coach (Zach) Yenser is the coach recruiting me and I spent most of my time with him but also got a chance to talk with Coach (Sonny) Dykes. Coach Yenser said that he's really interested in me and he wants me to come out for a day of camp so he can spend it working with me."
A Bay Area native, Dreyer said that he's long wanted to play in the Pac-12.
"I've always been a big fan of the Pac-12, growing up on the West Coast," said Dreyer. "There is a competitive environment and it's one of the top conferences in the country."
Wisconsin, though, caught his eye with an offer.
"Coach Chad (Kauha'aha'a) offered me and that was a big one because it's a great program with a lot of great linemen," said Dreyer.
Dreyer plans to camp at Stanford as well and is hoping to take some more unofficial visits.
"I'm looking to take some more visits and check out some of the schools interested in me," said Dreyer.
