The Vikings defense just got upgraded in a big way as the Chiefs have traded defensive end Jared Allen to Minnesota for three draft picks. It's not easy to make a defense like that a whole lot better considering how much talent the Vikes already have, but adding Allen takes things to a whole new level. He is one of the leagues best defensive players, and seeing how much money he will be making is proof of that line of thinking.
I hate to say this, but I'm already envisioning Jon Kitna getting sacked over and over by the Vikings defense. Like I said, they were good before, but with Allen they quickly have become one of the toughest defenses in the entire league.
