Looking at Shot Accuracy vs Possession to predict Goal Rates


Just wondering what the rest of you think. My thoughts are that the third chart showing FenSh% vs FenF20 gives a clear advantage to shot rate vs shot % although the author doesn't seem to acknowledge it. I really didn't understand the slant on the article given that the data seemed to indicate otherwise. I did, however, find it interesting to see the minimal correlation of Fenwick events against to goals against. Insight?
