Which 3 of these 4 RBs would you start?

I have Saquon coming back from injury going up against Arizona so questions but upside are there
Chris Carson who is really coming into his own and after the Dissly injury I think will get even MORE targets
Sony Michel who is finally averaging over 1 yard per carry going up against the Jets
and Tevin Coleman who seems to be the number 1 in San Fran but who knows with that backfield

Which of these three would you go forward with?

Barkley is a must start if he’s active, Carson likely won’t see additional tatgets w/o Dissly but is still a solid volume RB2 with upside, and Coleman is an absolute smash play vs Washington’s bottom 5 defense, specifically vs RBs on the whole as well as pass catching RBs
