Ideally this is what I want to see:
Another center, Andrews gets pushed around a lot, he is decent but we need someone bigger and stronger.
Tight end, Gronk is injury prone these days, we need another tight end next year next to Bennett if one of the two goes down, a blocking tight end would be ideal.
Next a strong safety, Chung is somewhat meh, I like the guy but he hasn't been doing much at all this year and we need a game changer safety that can get in there and deliver big hits and of course be able to cover as well.
We definitely need another corner, I am not sure how the Jones project gonna work out next year but we need another corner to start.
We also need another free safety. Dmc is getting up there in age and we need someone with speed and good football IQ.
Inside linebacker is a point of concern, I have 0 faith in Roberts to backup Hightower, also Hightower has been injury ridden all year, we need another run stuffing linebacker.
I think Van Noy can be decent at pas coverage, maybe not as athletic as Collins, but still serviceable.
Lastly, we need another slot receiver, Amendola is good when healthy but he hasn't been much of a game changer this year when playing, we are spending too much money on a guy that gets barely any receptions, if he wants to stay on this team next year then we need him to take a pay cut.
