I see a fascinating paradox when watching high level athletes perform. An observer can make a strong case that what they’re witnessing is effortless and free, yet at the same time can be described as contained, grounded, and giving max effort.
I think Nolan Ryan is a pretty perfect example. His mechanics look silky smooth, yet the players on the field, fans in the stands, and even the viewers watching a television broadcast of the game could hear a loud grunt being exclaimed from the pitcher’s mound every time his right arm propelled a fastball toward home plate. To this day, his fastball is still regarded as legendary and his longevity in the major leagues was also something to be marveled at.
