The argument is that the 5 in 58 stat is massively skewed by the majority of those 0-2 teams who were just plain s**t and were never going to play finals regardless of going 0-2. Of course, there's going to be the occasional good side that has a bad run of form/difficult opponents to start the season.Yes it is a correlation but it is 100% driven by a causal factor - the cause being a team is bad - this leads them to start 0-2 and miss finals - I can't fathom how anyone could see otherwise.
5 in 58 doesn't tell us anything significant.
