I was laughing at some of the "Frank Gore is immortal" jokes that have been floating around lately, and started thinking about other players that are still productive at 35. Could an all "Over 35" team be competitive? Here is the best lineup I could come up with of only players that have reached that age. I had to do a LITTLE shifting around(Brian Robinson is technically a DE, but he played some DT in 2016, so lets pretend he kicks back inside for our purposes). And Mulbach is a LS, but I assume he could pass for center. My options were limited!

Defense:

DT – Kyle Williams - Bills

DT – Brian Robison - Vikings

EDGE – Julius Peppers - Panthers

EDGE – Wake - Dolphins

MLB – Derrick Johnson - Raiders

OLB – Lorenzo Alexander - Bills

OLB – Terrell Suggs - Ravens

CB - Brent Grimes - Buccaneers

CB – Tramon Williams - Packers

S – Mike Adams - Panthers

S – Terence Newman - Vikings

Offense:

QB – Tom Brady - Patriots

RB – Frank Gore - Dolphins

RB – Darren Sproles - Eagles

WR – Larry Fitzgerald - Cardinals

C – Don Mulbach - Lions

G – Jahri Evans - FA

G – Richie Incognito - FA

T – Andrew Whitworth - Rams

T – Jason Peters - Eagles

TE – Antonio Gates - FA

TE – Ben Watson - Saints

K – Adam Vinatieri - Colts

LS – John Denney - Dolphins

Did I snub anyone? How would you fill out the roster? Players that have OFFICIALLY retired are not options.
And I apologize if this has been done before - I tried looking, but didn't see anything.
