Chuck D. Multiple Quotations

Surprisingly, games like chess and backgammon are tactically very similar to games like football and baseball. While the physical nature of the game is very different, the situational nature is strikingly similar. A football coach is constantly making decisions with respect to multiple variables (score, field position, down, yards to a first down, etc.). Sophisticated computer models and simulations were introduced in chess and backgammon more than 20 years ago, and much has been learned. To say that technology has revolutionized these games would be an understatement. There is absolutely no reason that ZEUS cannot have an equally revolutionary impact on professional sports such as football and baseball.

the most important and stunning discovery I made at art school was the ability to live by the single line... no shading, no multiple lines, no cross-hatching, no subterfuge. Just that line.

This is a tough problem, and there is no simple answer or smoking gun. More likely, there are multiple causes, and they may vary from species to species.
