Need RB Advice Big Time!

So I have injury problems at RB. Our league is a super flex standard.

I have Kamara, Murray, R. Jones and J. Samuels. For sure starting Kamara and…?

Watson is on bye, I have Kyler as my Qb and Ole Fitzmagic as my flex, gross right! Get rid of fitz and just start another rb?

Any advice from the great foot clan would be greatly appreciated.

Conner is out so definitely Samuels if there’s no one better on waivers.
