Readiness factor: The Jets' coaching staff and much of the roster will remain intact, which reduces the learning curve. But the Jets won't have training-camp bonding time at SUNY Cortland, an enhancement Rex Ryan and his players prized the past two seasons. They already pulled the plug on their upstate training camp and will convene at team headquarters in Florham Park, N.J.
Biggest challenge: All their free agents. The Jets have some biggies, most notably at wide receiver. They must keep young quarterback Mark Sanchez's support staff stocked with weapons, and receivers Santonio Holmes, Braylon Edwards and Brad Smith are about to hit the market. So are cornerback Antonio Cromartie and safeties Brodney Pool, Eric Smith and James Ihedigbo.
What a rush: The Jets quietly tied for eighth in the NFL in sacks last season but didn't have a fearsome presence in an overall defense designed to create mayhem. Of the 40 sacks they recorded last season, more than a quarter of them belonged to defensive backs and almost half were rung up by players who aren't under contract. The Jets released outside linebacker Jason Taylor (5 sacks). Defensive end Shaun Ellis (4.5 sacks) also has an expired contract.
