A lot of the comments here miss context and complexity and make some interesting and incorrect assumptions from them. 1. Big chances are not all the same. I don’t know the exact numbers but the conversion rate of a big chance can be anything more than about 20% and averages around the 30 to 35% range. That’s why xg is also a useful measure and needs to be used alongside this (as well as a variety of other deeper analytics that I probably dont really understand) 2. Big chances are both a construct of the players making the chances and the movement of the forward. Some forwards get a shit ton of big chances because of their skill level in terms of movement and dribbling etc. 3. Some forwards are elite in finishing but not necessarily in shot number - son is the absolute epitome of this. Most top strikers however are absolutely elite in shot creation and are more average in the finishing. Nunez is a good example. However players like kane, haaland and Salah are both shot monsters and above average finishers to differing degrees.
