Just one thing I think needs to be said:
I think the Jets overachieved last year. I honest to goodness didn't see them last year as SB contenders. Now I do, based on what they did in the offseason, but they still have holes.
Sanchez isn't a capable starting QB yet. You have to have one to win the SB. Their OL is the best in the league, but they lost their bread and butter in Thomas Jones. Greene MAY pick it up, LT MAY contribute, but we don't know.
They got more passing options, but Edwards has 1 good year in 2007 and nothing more, Holmes is a great receiver, but will be suspended, and we don't know how'll he perform with Sanchez instead of Roethlisberger...
At D, they simply don't have the pass rusher. They have to use intricate schemes, and Rex Ryan is great, but it showed against a veteran QB in Manning. Their secondary is great, specially with Cromartie, but it makes them vulnerable against the run.
We need to remember that they played the Bengals (no passing game) and won against the Chargers because their kicker missed 3 (THREE) FGs...
Like I said, I think they're a really though team, but they overachieved last year...
