Flex help! Who to start this week?

I have had no problems with my flex before Trever Lawerence got hurt because Brian Thomas Jr has been a fantastic flex. All of a sudden he’s basically out. I don’t feel I can start him with Mac Jones. I got to 10-0 with BTJ being a big piece of it.

My option are Juan Jennings, Deebo and Austin Eckler. Usually it wouldn’t be a question with Deebo but they are barely using him lately. What should I do?
