Probably more when every opponent is playing 3-2 zone against you every game, guessing outside offense, and having a higher outside defensive rating than your outside offensive rating.
I think mediocre flow/passing has to come into account here as well.Probably not enough open looks for the outside shots to go down.I agree 78 is still damn low. You even had really good shot distribution by position.More shots contested with poor-ish defense should have gone in.
