Some people are dumb. Some athletes are dumb. Some white athletes are dumb. Some black athletes are dumb. All truisms.
I wonder about Randle.
Caveat: for some it affects their ability on court, for others it doesn't.
It seemed to me that Derrick Rose has actual learning disabilities, but I don't think it affected his hoops.
I also recall Adonal Foyle looked positively impaired, but turns out he's quite the all-around scholar, poet, writer, businessman.
So I could be wrong about Randle. But my impression isn't based on his skin tone. Perhaps not surprising that someone like kiid doesn't actually comprehend racism.
Physical limitations: Randle has short arms which affects his ability to block shots and shoot over folks. Probably also costs a rebound or two a game. ZBo for instance had the bulky bod but combined with long arms.
Otherwise, if you don't think that some/many hoopsters put more attention in off-season conditioning, and apply themselves with more focus and aggression in a contract year, than I think you're living in denial. When there is $5M - $10M - $20M at stake (an extra guaranteed year), folks can get plenty motivated. Once a guaranteed $60M contract is signed, some naturally ease up some, enjoy the off-season more, coast a bit. Human nature. Some folks are highly self-motivated. For most it's a combination of self- and outside motivations, and money is a big incentive and validater.
My best guess is Morris wouldn't have been as prepared, conditioned, focused if this wasn't a contract year. He had extra motivation and put in the off-season work. It's hard to bust your tail a full season and dedicate yourself in the Summer as well. And do that every year. Folks get burned out. Or lazy. It's easier to slack off some. Morris playing for his last long-term contract and last big payday had one last offseason to push himself. And then focus for the season. Congrats to him.
So can we do a sign and trade with Morris, so that a team would get him locked in for a few years, if they so wanted? The SnT rules have changed and I don't think we can ... but maybe ...
