It doesn't have to be Yale, but it helps to have something stored in life's safe-deposit box for later use.
I have heard sports commentators say that the Patriots couldn't have tampered with the balls, because the game proved how vastly superior they were to the Colts. I think people have short memories. In 1972 President Nixon authorized and ran the Watergate break-in at a time when the world knew he was going to get a smashing victory over McGovern. It is the same syndrome. Deflated balls and burglary/break-ins happen totally aside from the Need for such actions. Things like this get done because they can be done, or someone thinks they can be done. Fools, to risk so much on such a stupid action.
