"Football" at EVERY level is a hotly contested, physically demanding and challenging, competitive exercise between opposing efforts. It never has, doesn't now, nor likely ever will require absolute perfection, although is often decided by the level of performance excellence and skill the contestants are able to consistently demonstrate. It is played out on an open field, often subject to variable weather conditions and other unpredictable obstacles challenging competitors.
Adapting to, and overcoming, designed, and/or, unpredictable obstacles is a major challenge to competitors which adds, significantly, to the general appeal of the effort and nature of the competition. Seeking excellence, through a rational pursuit of improvement is an appropriate objective, but expecting, or pursuing, absolute and consistent perfection in execution is likely a serious impediment to the long-term enjoyment, or appeal of the contest.
