Several of the Vikings’ top offensive players went to Southern California. Cordarrelle Patterson headed to Northern California.

Quarterback Teddy Bridgewater, tight end Kyle Rudolph, running back Jerick McKinnon and wide receiver Charles Johnson were among players who got together for workouts last month in suburban Los Angeles. Patterson was scheduled to join them before deciding to go elsewhere.

“I feel like I needed to work on something different from what those guys were doing,” the 24-year-old wide receiver said Monday during the second week of voluntary offseason workouts. “So I went to San Francisco.”

Patterson honed his game there as he tries to bounce back from a disappointing season. After catching 45 passes for 469 yards as a rookie in 2013, many were expecting Patterson to have a breakout season in ’14. Instead, he had just 33 catches for 384 yards while losing his starting job.

“This year is going to make me or break me, and I hope I step up and have a good role in this offense,” Patterson said.

Vikings coach Mike Zimmer had said after last season he hoped to have a notable football individual mentor Patterson but wouldn’t give a name. Patterson declined to provide details on that Monday or even confirm he worked with such a person.

Patterson, though, touched upon some of the skills he has been seeking to refine.

“This whole offseason, I spent a lot of time just thinking to myself, ‘How can I get better?’ ” he said. “I just want to let my game speak for itself. I just focused on the little things that really matter, and I hope this year will be way better than last year.

“Just route running. Growing up, I was always athletic and could just do anything. I’m in the NFL now, so I just have to focus on my craft and just work at route running, getting in and getting out of breaks and stuff like that.”

Last month, the Vikings shook up their receiving corps, acquiring Mike Wallace from Miami and releasing starter Greg Jennings. Wallace and Johnson are expected to enter training camp as the projected starters.

Patterson said he will miss Jennings but likes the speed Wallace brings to the offense. Wallace, a former Pro Bowl selection, hopes he can help Patterson bounce back from his disappointing season.

“Definitely, I’m going to,” Wallace said. “We’re going to work together a lot.”

As for Patterson, he will return to San Francisco later this spring for continued workouts. He remains determined to “get on a right path.”
