Arik Armstead took a tour of the 49ers Museum on Friday and lingered next to the exhibit featuring Justin Smith's No. 94 jersey. It wasn't the first time he'd come across it.
Armstead said he recalled his coaches at Oregon putting on film of Smith and ex-49ers defensive end Ray McDonald, who were part of a 3-4 front line that was similar to what was taught at Oregon.
"I've watched those guys do it," Armstead said, "and I'm looking forward to continuing to study them and seeing how they did it at a high level. And (I'll) try to take things from them and add it to my game."
Because the University of Oregon's class schedule will run through May, NFL rules prohibit Armstead from joining team practices until early June. Still, the team's first-round draft pick said he didn't expect a steep transition when it came to learning the playbook, which is similar to the Ducks'.
Never miss a local story.
"They have their own little wrinkle to it," he said of the 49ers' system. "But the base of it is similar and similar play calling. They just call it a little different. I think I'll be able to familiarize myself and get used to it quick and make that smooth transition."
Armstead also already has acquaintances on the roster.
His older brother, Armond, played at USC, and Arik said several of the players on those squads are now with the 49ers. The list includes cornerback Shareece Wright, center Marcus Martin and tight end Xavier Grimble.
Armstead also knows outside linebacker Aaron Lynch -- the two could line up next to one another on the left side of the line -- whom he met on a recruiting trip to Note Dame.
Armstead drove the 120 miles or so from Sacramento to Santa Clara Friday with his mother and father, who toured the museum with him. Armond also lives in the area and Arik has another brother and a sister nearby.
Armond Armstead played one year in the CFL before joining the Patriots in 2013. He recently settled a lawsuit against USC that blamed a heart attack he suffered at the school on the misuse of the painkiller Toradol.
"My brother, growing up, I wanted to be like him when I started playing football," Arik said. "He was the best player in the city. I idolized him and wanted to be like him someday and become the type of player he was."
