FanHouse Aundrae Allison

Training camp is finally here and FanHouse breaks down the most important position battles heading into the season, team by team.

It says something about the Vikings roster that one of the biggest battle during this year's training camp will be for the No. 4 receiver job. The reality is that besides a lot of drama about Brett Favre and the quarterback situation, there aren't many positions where Minnesota doesn't have a clear starter.

And even more encouragingly, there's some pretty good depth at several spots. Chester Taylor is one of the best backup tailbacks in the league. Second-round pick Tyrell Johnson gives the team an excellent back-up safety, and Jared Allen's acquisition means that Brian Robison goes from being an every-down starter to a very useful backup defensive end.

On the best of days, this Vikings offense isn't very good. But we now know that Sunday will definitely not be the best of days.

Both starting wide receivers could miss the game while starting quarterback Tarvaris Jackson will be playing just a week after sitting out with a broken finger.

Wide receiver Troy Williamson will miss the game as he continues to help his family mourn the loss of his grandmother. Wide receiver Bobby Wade is questionable with a knee injury. If they both can't go, the Vikings will be left with the trio of Sidney Rice, Robert Ferguson and Andrae Allison. Rice and Allison have some long-term potential, but that's a group that won't make anyone forget the days of Randy Moss, Cris Carter and Jake Reed.

If there is a bright side, getting Rice and Allison extended playing time will help show the Vikings what they have for 2008, which is getting more and more important with every loss. But it also means that Jackson will be even less sure of himself in the pocket, which is a very scary thought.
