Waiver wire pick ups

In a standard league I have Murray and he might be out this week should I pick up C.Thompson, J.Allen, or Henry as a RB 2?

if you could i would pick up both J Allen and Henry. IF Murray is out start Henry. if Murray plays i would start allen

You would start Allen over Murray?

the way Murray is playing right now yes. Especially if he plays which means that he is playing on a bad hammy and playing on a bad hammy is one of the worst things you can do for an RB
