I think this entire discussion has gone in several directions not intended by the original question.
Also, I am seeing different definition of science and emotions.
For me science is not technology like bowling machines but it is technique, assessment of match condition/situation, and cold hard skill. Improvisation is also part of skill hence science.
For me, emotion is the desire to do well and win. Naturally, this desire would vary from individual to individual. However, that doesn't mean that desire or even strong will is a good substitute of "science" or technical skills required to win. The masters of the game had mastered their technique and skill side of the game first. Their technique and skill may or may not be "orthodox" but it worked for them and they had an array of skills for different conditions. Their emotion (desire to win and dominate the opposition) alone did not win matches; and without skill, they'd be like any other fan with a bowl of popcorn in his/her lap.
