Vikings fans!!!! I need some help!!!!?

I've been a Steelers fan my whole life, as well as a football card collector. I've recently completed my Steelers collection, I have pretty much anyone you can think of. Now that I have done that, I would like to do the same with other teams, so I have a great football card collection, rather than a good Steelers one. Anyways, I need some help figuring out just who to get for the Vikings. I already have Fran Tarkenton, Daunte Culpepper, and Chuck Foreman. Who am I missing? Anyone who is a fan favorite, all-time great, or just a guy who played one year but had a BIG impact. I do keep tabs on current players, so I won't be needing anyone who is on the team now. Thanks for any and all help!!!!
