Most Surprising:

Pittsburgh: I honestly thought that they needed to go 2-2 until Ben came back....now they are sitting in the driver's seat.
Kansas City: though they will probably fall off a bit, who can argue the great start
Chicago: I thought they would be terrible, but they are playing very well

Most Disappointing:
Baltimore: I know their record is decent, but I thought they had the best team in the NFL after a few new acquisitions.
Cleveland: I didn't think they would be any good, but I am wondering if they will even win a game now
Dallas: Although, they got a needed win last week, they don't look very good.

KC is the most surpising to me on the good......no one else really surprised me

Washington is most surprising to me on the bad......thought they'd be better

Most surprising to me on the good is Pittsburgh.

Most surprising to me on the bad is Dallas.

Kudos for KC to be undefeated, but they won in a monsoon against a better team and beat two losers.

Likewise, sucks for San Diego to be 1-2 but they lost in aforementioned monsoon and special teams killed them against Seattle.

Surprising : Pittsburgh, I thought they were missing a QB so far but they are 3-0

Disappointing : Tebow, I thought he would win a Super Bowl by now.

Dallas could have won every one of their games, same for the Browns.

Surprise:Bears, Chiefs, Steelers
Disappointment: 49ers

"Dallas could have won every one of their games"

true, but they looked like pure crap against Washington. That was one of the most anemic offenses I've seen from any team. When you have Romo, Witten, Barber/Jones (or not, considering they won't run the ball) and their crop of receivers, that was turrrible.

the disappointing 49ers are up 14-0 on the Falcons

Niners are 0-4 now. I didn't expect that. I thought they were overrated, but not an 0-4 team.
