The Minnesota Vikings traded away their only real insurance at the game's most important position Friday night, a reckless and vindictive move that indisputably weakened the team in order to avoid the appearance of impropriety on the depth chart. I haven't always praised Sage Rosenfels during his two year-career with the Vikings, but this preseason he proved to be the Vikings' only competent backup behind Brett Favre. He far outperformed Tarvaris Jackson, who apparently has a tenured position unaffected by his performance. Let's be perfectly clear: Rosenfels was traded Friday night to the New York Giants because he beat out Jackson for the No. 2 job. As crazy as it sounds, that's what happened.
