Yeah? Ive been waiting for a real response to JR Smith still. Crowder ain't that tough or that good of a defender.
Refusing to take a cheap shot on JR doesn't mean he's soft, it means he's not a dirty player. Rondo didn't try to dislocate Wade's elbow at any point, but that doesn't make him soft. Kobe didn't cheap shot Wade as payback after Wade broke his nose in the All Star game a few years back, but even the biggest Kobe hater wouldn't try to call him soft. I didn't see Steven Adams kicking Draymond Green in the groin for payback, but, again, you'd be hard pressed to call him soft
You're confusing being dirty with being tough. Taking cheap shots on players is totally unnecessary, and it doesn't make you tough, it makes you a cheap shot artist. Good/tough players won't stoop to that level just for payback (I'd actually argue that just brushing it off and not looking to return the favor shows a lot more toughness than getting payback)
Edit: As for him not being that good at defense, he was the 3rd runner up for the NBA All Defensive team, just behind Gobert and Klay and just ahead of Lebron (despite missing time with an injury and still being hobbled by it after returning). Even if you don't like Jae, saying that he's not that good at defense is objectively wrong
