Sports best suited to our analysis rely on a few basic physical attributes. Football is too complex. In no other sport is division of labor more evident. A football team is a collection of specialists, with an enormously broad range of athletic ability represented among its players. The running backs combine speed with explosive power.
Wide receivers are fast, agile and jump like gazelles.
On the offensive line conservation of momentum rules. Bulk and strength get the job done. Three hundred pounds of humanity does not yield easily. And because there is no black monopoly on bulk or strength, we find whites on the front line. Place kickers, punters, line backers, punt returners and more round out a team.
