I've been searching to see if this has been mentioned prior, but from what I can see it hasn't.
What everyone seems to miss is how Fritsch approaches the ball. First, he sprints to make position before the Geelong player. He then slows and drifts ever so slightly to the right, taking space away from his opponent whilst assessing if the ball will slow and stay in. As soon as it appears that the ball will stay live, he leans into his opponent with a slight bump giving himself space to gather and shoot with no pressure.
This is what makes Fritsch so special. His timing and bodywork are always underrated and is what makes him so dangerous.
