Let's start with the most important guy, Geno Smith, the second round pick in 2013. Geno has been so up and down for the Jets at quarterback his first two seasons in the NFL. At times he has looked brilliant, but for a good amount of his time with Jets he has looked lost. In year two, he did actually improve. He had a higher completion percentage, more passing touchdowns, way less interceptions (though he threw 76 less balls), and a higher quarterback rating. Once again, Geno Smith ended the year on a bright note, but you can't just play well in December if you want to be a starting quarterback in the NFL. As of now, Geno will likely compete with veteran Ryan Fitzpatrick for the starting job. Geno Smith has some things going for him. The team likes his fit in Chan Gailey's spread offense, Brandon Marshall has already begun training with him, and year three is usually when a quarterback takes that next step. The quarterback position is the biggest on the football field, and if Geno progresses this team will also.
The next major key is Jace Amaro. Amaro is penciled in as the Jets starting tight end, a position crucial in developing a young quarterback. Amaro was solid in his rookie season, catching 38 balls with 2 touchdowns. At times he was a major non-factor however, and dealt with some drop issues. The second round pick from the 2014 draft has major upside with a 6'5 frame and great athletic ability. The Jets need Amaro to become a more consistent option in 2015.
On defense the Jets need major progress from Calvin Pryor and Quinton Coples. Pryor was the 18th overall pick in the 2014 draft, but struggled for most of his rookie season. With the Jets poor secondary a season ago, he was forced to play in weird spots, and not play in the box like he should of. With the additions of Revis, Cromartie, Skrine, and Gilchrist, I expect Pryor to show who is truly is on the football field. I expect Todd Bowles to allow him to blitz and play over the middle and hit people. Jets need him to develop into a true strong safety. The next first rounder is Quinton Coples. Coples was a first round back in 2012, but has yet to truly reach his potential. Coples was moved to outside linebacker from defensive end before the 2013 season, and has struggled with it at times. This past season he actually set a career high with 6.5 sacks, but the Jets expect more. Outside linebacker is such a crucial position for this team, and an area I expect them to address in the draft. This may be Coples last year to show he can be a starter for the Jets.
