Playoff Flex - Who to Start?

Here is what I got for my roster this week, need a little help on the flex spot though. Who do I go with?

Ingram, Ware, Justin Jackson, Tate, Demaryius

QB - Winston
RB - Kamara, Elliot
WR - Landry, Allen
TE - Brate
D - Bills
FLEX - ???

I like Ingram here, he’s got a good matchup against TB, which proved to be a shootout last time they played. It would be a nice safety net for Kamara as well. My second bet would be Ware, with Jackson as my 3rd option. I wouldn’t start Tate or Thomas in my flex this week due to their volatility.

Appreciate the input!
