tiger williams scored 241 goals in his career and had 3,971 penalty minutes. with the way the game is going its hard to see that being accomplished again.
one of the interesting/weird things about sports is that prior to using a level of optimization that seem like common sense, there were so many oddball records that came from how casually the game was played in previous generations. like the pitching records in MLB. nobody was throwing full effort all the time and the mechanics were a lot less stressful on the body. when hitters with no real danger were up to the plate, it wasn't uncommon for them to be pitched batting practice caliber pitches and because the floor of talent in the league was so shallow, it wasn't a problem. now that pitching has basically maximized the load limit of the ligaments in the arm by reaching 100+ mph and even spin rate on breaking pitches requiring max effort, arms would literally snap off before being able to throw as many innings as the old timers used to throw. the funniest part is people calling pitchers "soft" these days for not being able to achieve those feats.
hockey is the same. the lack of optimization allowed guys like gretzky to score in torrents because defensemen were barely tolerable skaters and teams had two lines that probably weren't AHL caliber by today's standards. goalies hadn't thought to drop down to stop shots and everybody was out there in awful equipment that weighed 100 lbs. full of water. that's when your outliers truly were able to shine. they were just players ahead of their time.
basketball was the same. tall centers with athleticism were indefensible. steve kerr hit 45% of his career 3 point attempts and for whatever reason, nobody tried to maximize that by allowing him to shoot 15 of them per game. he would hit huge shots down the stretch of games and it was like he was some secret weapon off the bench as illogical as that sounds. it's laughable by today's standards and in another timeline, maybe we consider steve kerr among the best to ever play.
the remarkable thing about all this is that it's just a matter of perspective. these things that are self-evident now weren't even a consideration at the time. the evolution of computer based outcomes has changed the way everything operates. I think we're very close to the extent of which the human body is capable of without AI assistance or biological modification, and the conspiracy theorist in me believes there are some damn close things happening out there in secret among the top tier of the top tier somehow biologically maximizing their bodies to perform at absurd levels late into their careers.
