Of course. But if you had a time machine and had to pick either prime KD or prime Russell to put on a team you're building, you'd pick the latter? I think that's crazy. Russell had so many limitations, and I don't think he'd be a top player in the modern NBA.
At worst Russell would be Kevin Garnett in the modern NBA, but when comparing eras I think you have to bake in previous era players with modern NBA training.
