The New York Jets can finally breathe a sigh of relief as they've finally completed the first stage to building another season towards the playoffs. From adding Eric Decker to losing Antonio Cromartie and Rex Ryan's predictions, the Jets have completed a very interesting off-season. Now it's time to see and develop players to get ready for the NFL season. Here's who to watch out for during training camp. Dee Milliner- Milliner is key because cornerback is a very thin position for the Jets in terms of talent. They're counting on the second year cornerback to be the number 1 corner. The Jets face 3 of the best quarterbacks in the league this season, Aaron Rodgers, Tom Brady and Peyton Manning all against the likes of Milliner, the aging Dimitri Patterson and the inconsistent Kyle Wilson. No Darrelle Revis or Antonio Cromartie. That's why Milliner needs to step up. There's a reason they didn't draft or pick up a good cornerback because they think he's one of the best young cornerbacks. Now he needs to show up and prove it in training camp. Geno Smith- Geno comes into this training camp with his GM and coach hoping he gets the job and his players on his back. If he performs well he will get the starting quarterback position but if he doesn't his future as a Jet could be in jeopardy. This is the biggest competition for the Jets looking to end a 3 year playoff drought. Geno looked sharp on day 1 going 7/10 with one sack. Michael Vick who obviously didn't get as many reps went 2/5 with an interception and sack. And Geno won on day 1. But he needs to have a great camp especially coming off a strong end to last season. Now he's got Eric Decker and Chris Johnson to help and the team supporting him to make the coming days his. Both Geno Smith and Dee Milliner are key players this season. If they succeed the Jets can maybe get to the playoffs but if not, their job and as well as Rex Ryan's can be in jeopardy.
