I've been saying this for a while now, but the Jets really scare me. They're younger, stronger and hungrier than New England right now, and I believe they finally have that intangible "leadership" aspect at the two most important positions for that sort of thing (HC and QB) that they haven't had in the past.
The Jets have a solid team. Sanchez and Ryan were two great pick ups for the Jets. I expect them to be contenders both in the long and short term.
Jets biggest
potential problems at this point is Sanchez has never thrown a football in temps below 50. How will he handle it? -- we should know in a couple of months. And while the Jets (like in most years) have a very solid 1-22 they are weak on depth, which often detrails their ability to win late in the season.
As for the Patriots this year, Brady right now looks a lot like Peyton Manning did the first few games of the season last year. That wasn't meant as a complement of either of them. If Brady can shake off the rust and get his timing back and when Welker comes back the offense should be as dominant as ever.
As for the Patriots long term and being "old". Over the next two drafts, the Patriots have seven 1st and 2nd round picks. Reloading is not going to be an issue.
But the days of 2007 are over. This isn't gonna be a division where we know who won it, week 10 of the season. Its gonna go down to the 17th week.
