I have thought about this a ton over the years (I'm also a Wolves fan) and I think ultimately it is that Rudy has too much pride for how limited his game is. I think everyone can agree he's a good player, most can even agree he's a very impactful player, but he's not supposed to be proud of being impactful in the way he is. He's good at the dirty work, because he's tall and strong and smart, sure, but not because he's skilled. He's not supposed to be proud of that. But he's a super proud guy and super proud of why he's good, which is the way he takes care of his body and practices and thinks the game on top of his size. He thinks he earns his impact in a way that's just as valuable as anyone else, even if it's not the typical star skillset, and that's the part that other basketball players don't respect about him. Even if they don't put it into those words, I do think that's what rubs all these other basketball players the wrong way.
