Using our considerable Microsoft Paint skills, we have transformed Charles Woodson -- who was released today by the Packers -- from Green and Gold to Purple and Gold. You could argue that it looks like he's wearing a big purple smock, sweater or snuggie. That's not the point.
This is: Woodson is a free agent. The secondary, while no longer an area of CRITICAL need for the Vikings after some nice moves prior to 2012, is still a place Minnesota could think about improving. Woodson is 36 and was moved to safety last year as his coverage skills started to decline. Still, theoretically at least he could play either position.
Even an on-the-downside Woodson could be a useful pick-up for a team that does have a history of grabbing veteran Packers.
