Then pick your own. Should be easy, right? Here's the rules:
A) Duncan has to have done it "a lot" of time (preferably more than 30)
B) None of the "Big Four" of Barkley, Malone, Shaq or Olajuwon have done it more.
For Example:
The Proverbial "Big Game" from Shaq would be 30 points, 15 rebound and 2 blocks. If I look it up:
1 Shaquille O'Neal* C 79
2 Hakeem Olajuwon* 71
Shaq did it 79 times (a lot) and more than anybody else. Duncan's at 5th with 30 times.
Another example: The proverbial "Barkley Game" is 26 pts, 12 rebounds and 5 assists:
1 Charles Barkley* F 98
2 Karl Malone* F 97
3 Kevin Garnett F 75
Duncan is 8th at 46.
So YOU pick the criteria. Do your best. But Im warning you its a waste of time. You cant fabricate dominance.
