I think he would be an improvement i'd say after watching some Texas games. That defense is out of position so damn much and gives up odd man rushes like candy. Also not playing at all for weeks or months gets people rusty. Stars might need him again at some point and if he hasn't played actual hockey games in months he might suck for a while. They don't have to do it of course but its something to consider. Hanley clearly has no chance of playing in NHL games while everybody else is available .
