The Stiebler vs Jesse Owens poll got me thinking, especially after someone mentioned that Owens was as dominant in one day (B1G championships) as any athlete has ever been.  So what ARE the most dominant performances ever?

Some off the top of my head: Larsen throwing a perfect WS game, David Robinson's quad-double, Clemens 20K game, Wilt's 100, Steve Young's SB.

Any others?
