At the midway point of the season, how are we feeling about re-signing these players on expiring contracts?

Due to Nick Caserio's strategy of utilizing 1 and 2-year contracts, the Texans have quite a few players on the last year of their deal. While this question will be the most relevant at the end of the season, I wanted to see how we're all feeling about who we would want to re-sign not that roughly half the games have gone by. Here's the list of relevant guys on the last year of their contract:

OFFENSE

TE Dalton Schultz

T George Fant

RB Devin Singletary

WR Noah Brown

DEFENSE

DE Jonathan Greenard

DE Jerry Hughes

DT Sheldon Rankins

DT Maliek Collins

DT Hassan Ridgeway

LB Denzel Perryman

LB Blake Cashman

CB Steven Nelson

CB Shaquill Griffin

CB Tavierre Thomas

S Eric Murray

SPECIAL TEAMS

K Ka'imi Fairbairn

P Cameron Johnston

LS Jon Weeks

Of course, there's no way to keep everyone. On offense, Schultz has really broken out the last few games, so I'd like to see us attempt to retain him. I also wouldn't mind bringing Singletary back. On defense… yikes, that's a lot of free agents. This is likely Jerry Hughes' last year with us, and I'm a bit back and forth on Greenard. I'm fine with letting both of our starting DTs go, but I'd like to hold onto Ridgeway as good depth. Perryman will likely be out the door next year, but Cashman could get re-signed. As much as I'd like to keep Nelson, he may try to get one last good contract with someone else next year, so he may be let go. In terms of special teams, I'd like to see us bring that whole unit back, as they have been fairly reliable (when not injured). What do y'all think?
