"It feels really good," Alfieri said of the offer. "They are one of my top schools. They are just really good academically and a really good football program. They have a great location, great coaching staff."
Alfieri received the good news from defensive line coach Randy Hart.
"(Hart) is the recruiting coordinator for my region," Alfieri said. "After that I talked to three or four other coaches. I'm calling Coach (David) Shaw in a couple of days."
The Cardinal are one of a few schools that are keeping a close eye on the 6-foot-3, 210-pound prospect.
"UW and Oregon State are both recruiting me pretty hard I'd say, and Stanford," Alfieri said.
Oregon State was Alfieri's first offer, but the two-way athlete also expressed interest in another in-state school.
"Being from Oregon, I'm definitely interested in Oregon," Alfieri said. "If they showed interest I would love to visit their school."
Alfieri is planning a busy summer by traveling to several camps on the west coast, one of which could include a stop in Eugene.
The junior is staying in shape with track and lifting on a daily basis. Three to four times a week, he sees a private coach to work on his speed and explosiveness. So far, Alfieri said he's enjoying the recruiting process as a whole and is taking in every moment.
"It's great to establish relationships with all of these coaches and learning about all of these great schools," Alfieri said. "I'm really just soaking it all in and taking advantage of every small opportunity I get."
As far as when a decision could be made, Alfieri said he is being patient and biding his time.
"I'll take my time with it," Alfieri said. "I'm not ready to make a decision yet."
