Since the AFL and NFL stopped having separate drafts in 1967, the Minnesota Vikings have only had the #1 overall selection once. . .and they didn’t even get it because they were bad. They got it because of the trade that sent quarterback Fran Tarkenton to the New York Giants. They had the #1 overall pick in the 1968 NFL Draft, and they used that select offensive tackle Ron Yary.
Yary went on to a Hall of Fame career with the Vikings, being inducted in Canton in 2001. Over at NFL.com, Elliot Harrison has gone through and ranked all of the #1 overall picks based on their careers.
