I am very excited about the power ranking in NFL week 4. It is going to be a bit difficult to call. Going into week 4, there are 7 teams that are undefeated, but some of those teams are said to so far be untested. The New Orleans Saints and New York Jets, both undefeated, will face off on Sunday. The Denver Broncos will face off against the Cowboys (2-1) although there are claims that the Broncos haven't been tested yet. The Indianapolis Colts will face the Seahawks at home, the Baltimore Ravens (3-0) will take on the 2-1 Patriots, but the big buzz is over the Minnesota Vikings. The new look Vikings will be facing the Green Bay Packers – Brett Favre vs. his old team – which means this will be one for the ages. Many would give payday loans to get on the 50 for that game.
