It depends on who he's guarding but I think you have a point. Down the stretch he was on Grant Williams who is a knockdown corner shooter, (42% last season). You can't really help too far off him. Playing him on the corner works great if the guy he's guarding is a weaker shooter but I would have rather seen Victor at the 5 down the stretch guarding Lively so he could just play drop and protect the rim instead of having to worry about Grant Williams out on the perimeter.
