I thought it might be interesting to have a thread where we wrestle with how to quantify the impact of Marcus Smart. Smart seems like he has a consistently positive impact on winning. His on-off stats support that. But his traditional box score stats are bad and most advanced stats tend to agree. This raises a few questions: Is Marcus Smart actually good? Assuming he is, how do we measure that, and, maybe, what might that teach us about measuring basketball impact more broadly? Assuming he is again, is he inflating BPM/RPM stats for his teammates instead of himself? Building on that last question, we've talked in the past about a possible Brad Stevens effect. Is there a Marcus Smart effect?
