If Kane had an 70% shot accuracy would it still be misleading?
Depends on what argument you were building around that statistic. Say a player takes barely any shots and only takes on ones which are considered easy goals, then he may have a high shooting %, but that doesn't actually necessarily mean he's good at striking a ball.
Hence why Van Persie has a shooting accuracy of 42% in his Premier League career, and I consider him to have possessed some of the best shooting technique the leagues ever seen. He took on hard shots other strikers would turn down.
