Lineup HELP to decide my playoff fate

HALF-PPR. 10 team league.
I have a solid team, but I may miss playoffs (5-5) as I am on the outside looking in and playing #1 seed this week and #3 seed next week. I am having trouble setting my roster (namely QB, RB2 and FLEX).

NOTE: Baldwin banged up his hammy, so I was thinking of starting Howard over Coleman so that I could flex Coleman if Baldwin is a surprise scratch on Monday.

Currently Starting:
QB- Prescott
WR1- A. Brown
WR2- Julio Jones
RB1- Ingram
RB2- T. Coleman
FLEX- Baldwin
K- Streaming Butker this week
Def- Streaming Den this week

J. Howard
A. Morris
G. Olsen
K. Allen
NE DEF (Rostering for matchups Mia, Buf, Mia in next 3 weeks)

I’d start Cousins over Dak just cuz the Eagles D will probably get to him just like Atlanta did. And NO defense is good but Cousins played good against the Vikings last week so he should be able to do fine against the Saints.
