Conversion rate is a weird one though.
Take two similar strikers, like mandzukic and giroud and it is fine because they take similar chances.
Balotelli take all the free kick and takes a shit load of shots from distance, not all chances are created equal or taken equally.
C.Ronaldo only has a 16% conversion rate, does that make him and average finisher or is he taking low % shots more often than not?
