Rookie to make biggest impact

The Eagles made some need draft picks early and late in Chip Kelly's first draft  drafting OT Lane Johnson 4th overall, Zach Ertz a big tight end from Stanford, Earl Wolff from NC State who resembles Dawkins at the safety position and many more prospects but which one will make the biggest impact and help the Eagles win in their first season? Chip Kelly seems to be leaning towards using a two tight end system a lot like the Patriots did with Rob Gronkowski and Aaron Hernandez who I will not comment on.....I think everyone reading this knows what is going on. The Eagles signed James Casey and still have Celek on the roster so yes the snaps might not be as much for Zach Ertz but with Casey being so versatile, Ertz if impressive in the preseason could easily beat out Celek for the starting job as Kelly is not afraid to make changes. Ertz rare size and speed for a tight end resembles a Jimmy Graham or Aaron Hernandez....sorry again for mentioning his name in this tough time but Ertz could pan out to be like these guys. I believe Zach Ertz will be the most impactful rookie, yes Lane Johnson will probably start at right tackle but he is a bit raw still. Bennie Logan is a interesting situation, he is coming in to a new 3-4 defense which might require him to start at DE along with Issac Sopoaga and Fletcher Cox so he may be very productive but he is not a sure thing to get on the field a lot with Cedric Thorton and Vinny Curry on the roster as well who in my opinion, could both breakout in Curry's second year and Thorton's third on the Eagles.Other than Zach Ertz a player who could make a really big impact is 7th rd pick Jordan Poyer, Carry Williams and Bradley Fletcher do look like the starters as of now but with Williams missing time and both Williams and Fletcher have not been consistent starting corners, Poyer's aggressive press coverage skills could get some good playing time in the slot and outside if Williams does not perform. Brandon Boykin showed some good skills last year in the slot position but there were times that he could not handle his man, just look at week 3 against the Cardinals, Boykin got absolutely destroyed by Larry Fitzgerald so no spot on the Eagles corner back depth chart is taken they are all up for grabs. Many Eagles rookies this year are going to be on the field but one that might be in due to injuries and could earn a spot is safety Earl Wolff who was very impressive in NC State with a total of 119 tackles and was a absolute tackling machine. Out of all the rookies on the Eagles roster, I give Zach Ertz the edge to be the most productive for many reasons with his physical skills and with a offensive head coach in Chip Kelly, he is set up to succeed in his first year maybe even better than 1st rd pick Tyler Eifert of the Bengals.
