Toronto Raptors guard Fred VanVleet (back) is listed as questionable for Friday's game against the Dallas Mavericks. He missed their last game on Wednesday due to back stiffness. His absence resulted in Scottie Barnes shifting over to the point guard spot. That is likely to happen again, assuming Vanvleet is unable to play. Chris Boucher would also see a boost in playing time and is worth looking at as a possible streaming option.
