The NFL (National Football League) is in full swing and many exciting stories have already begun to unfold.

Although the league opened just three weeks ago, teams have already surprised their fans, for better and for worse.

Seven of the 32 teams in the league are now 3-0 (3 wins – no losses).

But it may not be the teams you would expect.

Favourites such as The Seattle Seahawks, The Denver Broncos and The New England Patriots are 3-0, but so are The Kansas City Chiefs, The Miami Dolphins, The Chicago Bears, and The New Orleans Saints—four teams that didn’t even make the playoffs last year.
