I have to win tomorrow to make the playoffs. Who do I start?

I’m playing a good team so I’m going for all high ceiling plays. 10 team .5 PPR

My biggest decisions are KW9 or Christian Watson at Flex?

Darren Waller or pick up someone like Juwan Johnson?

Start Vidal AND Hampton?

Maybe there’s some holes in my thought process? Please point em out to me and build your best lineup..

QB: Brissett RB: Hampton RB: Harvey WR: Nacua WR: Pickens TE: Waller Flex: Watson Flex: M. Wilson K: McLaughlin

Bench

KW9 Charbonnet Dart Vidal C. Rodriguez
