IF the nhl goes to 100 games season, people will care what player do during the first 82 games of the season for a while, they will also care about what player do in their first 82 games they play during the longer season but the different will feel obvious and evident for a while.
Richard had to do it in the season first 50 games, if someone beat 92 goals playing only 80 games but taking 95 season game to do it it will be brought up, it is not exactly the same thing.
Same for 50 consecutive games if there a summer break inbetween them versus what Matthews did or the first 50 games played versus the 50 best stretch game in a season, etc.... all have some small difference.
Has for caring, obviously never any reason to ever care what unknown adults pushing pucks in net do or not.
