Over the weekend, Bleacher Report surfaced a video suggesting Adrian Peterson — according to an anonymous, high-ranking NFL official — wants to be traded from the Vikings to the Cowboys. That report came not too long after an ESPN story in which Peterson said he was “uneasy” about rejoining the Vikings. On Monday, there was this beauty: Peterson’s agent and Vikings vice president of football operations Rob Brzezinski reportedly had a heated exchange at the NFL Combine, during which the agent (Ben Dogra) said Peterson would never play for the Vikings again. So what’s really going on here? Well, the short answer is this: leverage is power, and for a long time Peterson has had neither.
