It's said NFL stands for Not For Long.
Sixteen National Football League teams entered Week Two of the season with unbeaten records, but they didn't maintain that status for very long. Nine of the 16 fell by the wayside Sunday, including the Baltimore Ravens and Chicago Bears, who had impressive opening wins on Kickoff Weekend against strong opponents.
Aside from the Buffalo Bills, the surprise team so far is Washington, which is 2-0 after Sunday's 22-21 home win over the Arizona Cardinals. Now, though, coach Mike Shanahan's Redskins must take to the road for a Monday Night game at Dallas after winning twice at home.
Home teams went 10-5 Sunday afternoon after going 10-6 in Week One.
Cowboys 27, 49ers 24
The scoop: Playing with a fractured rib, Tony Romo hit Jesse Holley on a 77-yard completion on the Cowboys' first play of overtime that set up Dan Bailey's winning 19-yard field goal. Bailey kicked a tying 48-yard field goal as time expired in regulation. Miles Austin had three touchdown receptions among his nine catches for the Cowboys, leaping over a defender and diving into the end zone to pull Dallas within 24-21 with 6:55 to play.
