Erasmus, etc.

Rookie defensive end Brian Robison had two of the Vikings' six sacks in Sunday's 24-3 win over Atlanta, but that won't factor into the team's decision of when to activate starter Erasmus James.

"Once Erasmus is ready to go, he's out there," defensive coordinator Leslie Frazier said. "It won't affect what we're doing with Brian. He'll still get reps, but you want to get your best 11 on the field. And when Erasmus is healthy, he'll be one of our best 11, without question. He's a special talent and we need him."

Frazier said the Vikings are being cautious with James, who is coming off two surgeries on his left knee and was inactive for the opener.

Asked if the team could wait until after the Week 5 bye to bring James back, Frazier said: "It's a possibility. We'll see how he progresses over the next few weeks. It could happen any time. We've just got to be cautious and at the same time look for that opportunity to get him on the field."

Some other notes from the afternoon practice and morning interview sessions:

--James was the only player missing from practice.

Running back Chester Taylor (bruised oblique muscle) was in uniform but did not participate in any drills during the open portion.

--Offensive coordinator Darrell Bevell said the offense is still a work in progress and that he's more interested in wins than statistics.

"Do I want to put up 35 points a game? Absolutely," Bevell said. "Do we have the ability to do it? We do. There's still just little details that we're working on. The guys are working hard. They're improving each and every time that they go out in practice. It's just a matter of time before we get over the hump."

--Running back Adrian Peterson and Lions wide receiver Calvin Johnson are two early candidates for NFL rookie of the year, but Peterson said he isn't looking at Sunday's game as a personal competition.

"I'm not necessarily going out to prove anything," Peterson said. "The main objective is just going out there and getting a W."
