Stumped about how to flex my flex spot during championship

I’m in my fantasy championship for the first time ever, and I have Breece Hall, Garrett Wilson, Adam Thielan, Jerome Ford, and Tyjae Spears available to put in the flex spot for today. Breece and Tyjae are projected to score the highest in PPR, but Breece has been so wishy-washy over the course of the season and he’s playing the Bills. Same with GW.

A lot of people are saying Thielan could either go off this week or be hurt by Chuba’s injury because Bucs will redirect all defensive focus to the passing game. I know nothing about Miami’s rushing defense (Ford) and I just picked up Spears this week on waivers so I’m not too familiar with his gameplay. Any and all help appreciated as this could make or break my championship!
