Flex Help - #3 vs #1 (juggernaut!)

Full-PPR. I am currently in 3rd going against the #1 seed who is a Juggernaut. He has Maholmes/Hill stack, Allen as WR2, Cook as his RB1 , and Gordon as RB2.

I need my little guys to ball out this week. Any suggestion as who to play in my flex? I feel like I need a high upside.

QB - T. Hill (I also have wentz but he has been dog doodoo)
RB - Gibson and Sanders
WR - Adams and Kupp
TE - Waller
DST - Steelers
Kicker - Blankenship

Bench - Chark, Crowder, C. Davis, Jeudy, D. Samuel, S. Ahmed, B. Scott
IR - Wilson Jr., J. Jackson

I was thinking either Ahmed or Chark, but C. Davis has been playing very well and putting up points. Any suggestions?

Bump for help

That is a tough matchup to go against but i dont think Davis is your ceiling play. Chark has done it a couple times and Ahmed could get in the endzone twice so one of those just what position would you rather rely on

Chark now has Mike Glennon throwing to him. Ahmed is going up against the Jets…

I would start Chark. Don’t sleep on the Jets run D. As bad as they’ve been this year they’re solid against the run
