Looking at the Jets so far this preseason (yes, I know it is preseason and you can't make firm conclusions), they look much of the same as the regular season last year. They have a great defense (although Rex Grossman picked apart the defense a bit), a very good running game, and a liability at QB.
The Jets took a big hit tonight since they lost Calvin Pace indefinitely. Looks like he may be out 4-6 weeks with a broken foot, but it could be longer and he might not be nearly as good when he gets back.
