The only law that we all must obey is Newinn's.
All of us that is except for #42. Rivera is the one entity on the planet (except for maybe Gretzky) that blatantly disobeys Sir Isaac's rules about the mechanics of the physical universe. We'll never, ever see a hurler coax a baseball to defy the laws of gravity like Mo.
The Yankees will adapt to Mariano's absense when that time has come but bb fans will never see another closer of his caliber and class.
Fixed it for ya Prof
