Waiver troubles

Im in a .5 PPR. Picked up Bilal Powell off waivers, just couldnt let him sit there. My other RBs are J. McKinnon, C. McCaffery, Matt Forte, and my WRs are T. Hill, M. Jones, M. Sanu, Tedd Ginn, and C. Kupp. Should I be holding on to Bilal Powell? Keep/Trade/Cut?

I have in my league and have been trying to trade for the past few weeks. He keeps on putting up decent flex and looks like he will again this week against a bad Tampa bay team. After this week though it is looking tough matchup wise the rest of season

Is it worht holding both of the NY Jets RBs though?
