Goat's of Sport

Here I am watching modern-day gladiators, As they compete and look to win. While various opinions are bantered about, As to who might be the greatest, by comparison. This subjective search is ever-changing, With the ebb and flow of time. Not to mention some defining ambiguity, Such as, how is the greatest achieved in the climb? Some may look to prolonged winning habits, Whether individual or belonging to a team. While others, look more to pure, physical talent, Breaking down skills and athleticism that others dream. Since there is an aspect of longevity, Built into the term, as if it's a crime. Maybe we should modify the acronym's expectation, And seek only the 'Greatest of A Time'.
