To add, IMO, Treliving is the type that always looks big picture. I doubt he risk bringing Smith back if there's a risk we lose him before playoffs due to re-injury. I think he knows very well the point is to use Smith as little as possible during the regular season, and as much as possible during playoffs. I really hope Gilles and Rittich develop and learn via this trial by fire and take the reins in showing us one of them are ready to be a solid backup and take Smith's spot when his contract is over. It's probably one of the few true opportunities they'll get for a while.
