I'm going to go with the Saints. Great offense, good defense, great coach and elite QB.
The Jets don't have the offense to win a superbowl and Sanchez is still on the fence, imo. He's been terrible all preseason and he was horrible tonight. Typical Rex Ryan team. Loud and brash with a killer defense, but a subpar offense that cant do much but run the ball. Not going to work when many teams can hang 40 on you night in and night out. Sanchez is still running the most basic of plays and has real trouble checking down. he could improve, but it's unlikely that he has what it takes to win a SB this year.
The Vikings won't do it because of Farve. Highly unlikely that he will put together a season like he did last year. He's going to have to fall off a cliff at some point and this year might the year that it happens.
The Colts are always a threat, but they lost Sanders AGAIN and Houston exposed them yesterday. They can't stop the run. Injuries will test their depth. In todays NFL, lots of teams have potent offensive threats coupled with better defensive options. That said, with Manning there is ALWAYS a chance.
I do not watch the packers, so I can't comment on them.
I really liked what I saw from that Patriots yesterday. Their O is top 3 caliber and the past three drafts have proven to be very succesful. They have two stud te's now, an electric return man, a great wr core and the defense is young, fast and aggressive. Mayo and Spikes make a great tandem and Guyton has really emerged. Brady is back to spreading the ball around and hitting the open man. They have two nasty safety's, two very good starting corners and quality depth on the line. However, their youth and lack of experience will not allow them to win a superbowl. Their schedule is a bitch too. Also, the loss of Ty Warren/Mankins on the lines hurts. I'm picking them next year.
