Langford is in an awkward phase of his development right now.
He has no role off-ball, but he's not yet good enough on-ball to take touches away from any of our other guys. So he doesn't really have much opportunity to make use of his nascent ability as a ball-handler. The result is that he just has no job on the court other than defense. That works if we're at full strength... we can throw him out there with Fournier, Thompson, one of the Jays, another shooter, and his lack of offensive output isn't as problematic. But when we are as short-handed as we have been over the last couple of days, it's a much more glaring issue.
A real offseason and a significant amount of practice time would do him wonders, so I just hope he stays healthy. I do believe he has a high ceiling, and I also think the team is really high on him, but he has a long way to go to get there.
