This gives a limited definition of being a two-way player. Rudy is elite offensively, it’s just that it’s not the way you’re traditionally used to. He’s not Mutombo on offense. He’s not Samuel Dalembert. He’s not Ben Wallace. It’s like saying a guy isn’t a defender because he isn’t a lockdown guy you put on the best player. Perhaps you need a lockdown guy or want more of them, but you can’t be so narrow in a definition where anything that isn’t a lockdown guy therefore isn’t a defender. Same goes for offense. He’s not offensively like Jokic or Embiid, but he has his own value. You can make a strong argument that his type of offensive skill set could be preferable, depending on the rest of the roster makeup, because his offensive value isn’t tied to his usage and he can facilitate an offense adding even more positive guys who are higher usage.
A better question is how many other good offensive centers can have the same level of impact he has offensively if they had his usage? That’s the issue here. Everyone “good” on offense wants to fight over usage. Here you can put someone into your offensive who is every bit as good, if not better, without affecting your usage.
