Questions come from accounts, not the open internet. It keeps the mailbag readable and means we can tell you when yours is answered.
Everyone says Byram is a defensive liability. His rating says otherwise. Which is it?
Both, in a way that only separates once you isolate him. His on-ice numbers are poor and his isolated defensive rating is not — which usually means the minutes are hard rather than the player is bad. That is the gap the model exists to measure, and it is the kind of question this mailbag is for.
