If he gets a starting spot, he's certainly worth it. But he's probably not going to be up for that long, so like it has been said, I wouldn't burn a high waiver priority on him. Still, if you've got some WW fodder sitting around on your roster, go ahead and add him on the off chance he stays up and gets good playing time.
