Vikings pre-season

Normally, I am not a big NFL training camp guy. I find our obsession with football to me more annoying than anything else. I would prefer that the main sports story of the day be the Twins' actual game, then a Vikings' practice, but whatever. This year, though, I find myself slightly more interested in the Vikings. I'm not sure if it is because of the failed Favre saga, or the fact the Twins are in a mighty struggle, but Vikings Training camp has me mildly interested.
I really think it is because I feel like the Vikings have a chance to be good this year. They return many key parts from last year and appear to me to be a solid quarterback away from being a really good team. Adrian Peterson is absolutely amazing. Percy Harvin could be fantasic. Bernard Berrian led the league in yards per catch last year. They have weapons on offense, and still have two of the better O-lineman in the league (Steven Hutchinson and Bryant McKinnie). Really, the only thing the offense is missing is a quarterback.
However, I'm confident whoever wins the QB job will be fine. Tavaris Jackson has shown at times he can be a player, and he should continue to get better. And Sage Rosenfels is a veteran, who should be able to manage a game decently. The Vikings do not need a pro-bowl quarterback. They need somebody to complete 55-60% of his passes, minimize mistakes, and hand the ball to Peterson and Chester Taylor. It isn't that hard. I think a more seasoned Jackson, or a acclimated Rosenfals, could fill the roll.
The Vikings defense remains solid, with the Williams Wall and Jared Allen on the D-line. I read the defense doesn't have any starting position battles, which speaks to the experience and ability of the players. They are a good enough defense to carry the team in a couple of games, but not all year long.
The Minnesota Vikings are just an intriguing team this year, in part because Favre isn't here. They would have been more interesting with him, yes, but without him, their only big question mark is the most important position on the team, where a so far ineffective young quarterback and a veteran second-stringer fight for the starting spot.
