I mostly agree with what you're saying. With average players and an average supporting cast, it's a prescription for failure. I do think there's some championship-level exceptions though, i.e. Perkins in Boston and Ben Wallace in Detroit. Given, both had excellent supporting casts and were playing in a different game than the one we watch today. On the subject, I think Okafor/Noel will be a really interesting combination down the line, and they're a perfect example of what we're talking about. Ideally, if you're a Sixers fan, you'd hope Jah's ability to dominate inside and draw double teams would open up some easy putbacks, cuts to the rim and spot up jumpers (assuming he keeps improving that shot) for Nerlens, while on the other end Nerlens could hide some of Jah's issues with help defense. I like the potential of this example because there is no going small against Jahlil. As Jay Bilas said, "You wanna put Draymond Green on Okafor in the post, he'll give ya 30."
