I think he's worth a flyer. He's supposed to be back this week. Your team looks pretty stacked but I would consider moving Sessions (Mo is back soon) or Salmons for him.
He had arthroscopic surgery with essentially a washout on both his knees, which isn't huge surgery. Most likely he'll play better than pre-surgery down the stretch since he should be in less pain. He was dropped in one of my leagues when surgery had been announced and I was able to grab him so we'll see how it turns out (dropped Daniel Gibson).
