Four teams that have a chance to rise this week

Now, here we are at Week 4 of this season, which is crucial for four teams.
Boise State, which faces Oregon State of the Pac-10, is seeking its fourth consecutive victory over a “Big Six” opponent, and the Broncos know that the Beavers are the last real obstacle to an unbeaten season.
South Carolina seeks its first 4-0 start since 2001, and that will require winning at Auburn, which has won all four SEC games it has played against the Gamecocks.
West Virginia is looking to gain some respect for itself and the Big East as it whole as it travels to LSU. The Mountaineers are 3-0 and trying to go to 4-0 for the first time since 2007.
Arkansas is hoping to avoid a fourth consecutive loss to Alabama. The Tide won by — what else? — four touchdowns last season.
