just chiming in. so with the same logic, Michael Jordan is generic since he patterned his moves to Dr. J, right? pati si Clyde Drexler ganun din.
also, i wouldn't say Shaq revolutionized the C position because after him, there was no one else to play the same as him or like other great big men like Hakeem, Ewing, Kareem, etc. he was the last great big man. he's more like Magic where there was no one else like him again.
When you say revolutionize you change something and the next generation tries to follow your example. Dun kay Shaq wala nang ibang naging dominant center or at least what they call a classic center.
