Percy Harvin took part in a big autograph event at Earle Brown Heritage Center in Brooklyn Center on Saturday and the Vikings second-year wide receiver stopped and chatted for a few minutes when he was finished.

The thing that caught our attention immediately was that Harvin looked noticeably bigger and in tremendous shape. Harvin said he's added about 10 pounds of muscle this offseason while working out in Florida. He said he weighs 207 pounds now but said ideally he would play at around 200 pounds this season.

"Normally when I workout I put on a couple of pounds," he said. "I wanted to be stronger. I know I'll probably lose some so I'll probably play at 202, 200. That will be good for me."

Harvin said he's excited for the upcoming season after winning rookie of the year honors and earning a Pro Bowl berth last season. He certainly made a smooth transition to the NFL both as a receiver and kickoff returner.

Harvin set a Vikings record for all-purpose yards with 2,081. He finished tied for first among all rookies in receiving yards (790) and receptions (60). He ranked fourth in the NFL in kickoff return average (27.5 yards) while returning two for touchdowns.

Harvin said his body feels fresh compared to this point last season when he went through a number of workouts for teams leading up to the draft.

"I know everything now so everything is going smooth," he said. "I don't have to do all the Combine stuff, the wear and tear. I'm just studying now so hopefully I will have a dominant impact next year."

The Vikings veterans will report for voluntary offseason workouts on Monday. The younger players began two weeks ago. Harvin has stayed in Florida and was non-committal when asked if he will take part starting Monday at Winter Park. Again, we stress the workouts are voluntary.

"I don't know yet," he said. "I talked to coach. I'll come up and workout a little bit. But we'll talk and figure something out."

It seems the only thing that slowed Harvin as a rookie were his severe migraines. Harvin has dealt with migraines since he was 10 and had several problems this season. He missed one game and a number of practices while dealing with severe effects. He visited Mayo Clinic late in the season seeking a plan for how to treat them when they occur.

Harvin said he's suffered from migraines at different times this offseason.

"It's off and on," he said. "Still working them out. Hopefully we'll keep working at it. My mom has had them for 30 years. They come here and there. It's just something that hopefully I can contain. But I've talked to a lot of doctors. I don't think there's too much that can stop it."
