Not Too Soft
Apologies for the digression- but I thought I'd do a little work with this one:
The 1955-56 league-wide PiM total was, in context, a freak outlier. Iz'not the biggest freak outlier of the 70 game O-6 era. [That distinction belongs to the 1964-65 season.] Still, it's clear at a casual glance that 1955-56 is not characteristic of the general run.
To use an outlier-numbers in furtherance of a counter-argument against a trend is an example of the "bikini-principle." What's revealed is suggestive... but it's what's concealed that's absolutely vital.
Average seasonal PiMs for the six-year span prior to 1955-56 were 595 PiMs lower than the average seasonal PiMs for the 11 year span 1956-57 to 1966-67.
Maybe it's possible that after the rule change, referees were actually more inclined to call infractions, feeling as though they weren't necessarily determining the entire outcome of the game with such calls.
