Bismarck’s epigram about diplomacy and sausage applies also to the way we Americans seem to feel about professional athletes. We revere athletic excellence, competitive success. And it’s more than attention we pay; we vote with our wallets. We’ll spend large sums to watch a truly great athlete; we’ll reward him with celebrity and adulation and will even go so far as to buy products and services he endorses. But we prefer not to countenance the kinds of sacrifices the professional-grade athlete has made to get so good at one particular thing.
