It's been an exciting season of football, and few people probably would have predicted some of the teams at the top, and others at the bottom. Who would have thought the Broncos would be unbeaten through four weeks and the Titans still winless after four games? This is a surprise by every means, and it's time to look at the top 4 football teams through the beginning of the year. Let's see who makes the cut. These teams will be listed in no particular order, as it's really hard to rank them definitively after four games.

1. New York Giants. It's fair to say that this team really hasn't played a bad game just yet. With a tough win at Dallas, this was their hardest game of the year and they handled it with grace. Dealt two or three other easy opponents, they'll need to be tested some more before we really know what's what.

2. Indianapolis Colts. Dealt with adversity after the loss of Anthony Gonzalez in week one, this team looks like it has no problems out on the field. Some solid wins through and through, they may be the AFC's best thus far.

3. Denver Broncos. I didn't think I'd ever be listing them here, but they are in fact unbeaten still. This is a great team that's completely overachieving, but it'll be interesting to see how they can fare against tougher opponents.

4. New Orleans Saints. An incredible offense, and possibly the best in the NFL. They manhandled the Jets in week 4, which says a lot.
