Going into his second NFL season, newly turned oLB Quinton Coples is pivotal to the Jets having a good season. In his rookie season he recorded 5.5 sacks, but they will need more than that this year. To have a great defense, you need some pressure of the edge, which the Jets are hoping Coples can provide. Double-digit sacks and getting Tom Brady on the ground should be goals for Quinton this season.
2) Stephen Hill
Another guy going into his second year, wide Receiver Stephen Hill could be the key to the offense. Santonio Holmes may start the season on the shelf, leaving Kerley and Hill as the team's best weapons at wideout. Hill got off to a great start last season, but ended up having a horrible season, as he dropped passes and couldn't play against good corners. The Jets will need to use his 6'4 and great speed this season to be a deep threat for them.
3) David Harris
Coming into last season, middle linebacker David Harris was considered a star. He had a bad season a year ago, as he looked slow and old. The 29 year old Harris is the veteran of the defense, and needs to be a leader in the middle. With an unproven DeMario Davis by his side, the Jets need Harris to regain his old form.
4) Mark Sanchez/Geno Smith
Whoever plays quarterback for the Jets will be the biggest key. The competition is still going on between Sanchez and Geno, and whoever wins will have a lot of pressure on their shoulders. THe Jets won't win a lot of games if their quarterback turns the ball over a lot, as evident last season, and should look to the gay who turns it over less during training camp and the preseason.
5) Chris Ivory
I loved the Chris Ivory trade. Ivory has never gotten a chance to be a full-time starter, but has averaged 5 YPC in his career. During his rookie season in 12 games he rushed for 700 yards. In this offense I think Ivory rushes for 1,300 yards and gets the Jets back to the ground and pound. If Ivory emerges as a star, everything else will be easier on the Jets offense.
