Are Tony Jones and Le’veon Bell must adds for Gus Edwards and Kamara owners? (Redraft)

Went WR/TE heavy first few rounds of my draft but it left me with slim RB depth. My RBs are Kamara, Gus Edwards, Ronald Jones, Jamaal Williams, Nyeim Hines. I was thinking about putting a claim in for Le’veon Bell and Tony Jones dropping Williams and Hines in order to handcuff Kamara and Gus? Thoughts?
