Zero rb strategy, should I trade for K Williams?

10 man ppr. My team

Qb: Kyler Murray, Drake Maye

Rb: T Pollard, A Jones Sr, Jk Dobbins, Ford, and J Williams (Dallas)

Wr: Lamb, BTJ, Evans, Tet Mcmilian, R Pearsall, Pittman Jr.

Te: G Kittle

Plan is to try to trade Evans or Tet for Kyren Williams. Thoughts?
