The careers of professional athletes end, as a general rule, about the way Hemingway described going bankrupt: slowly, then all at once. An injury — say a knee sprain that happens in a February 2009 game in Utah — occurs, never fully heals, becomes a chronic, lingering source of discomfort, then, as the player fights through it, adjusts, maybe unconsciously to mitigate the pain, a host of other maladies spring from the adjustment: calf strains, tendonitis of various stripe, back pain.
Bio-mechanical breakdown ensues.
Eventually, they’re a shell of themselves. A copy of a copy; like that Michael Keaton movie, but even harder to watch. A season later they’re on a golf course.
Kevin Garnett, for reasons that aren’t entirely clear, is not on a golf course right now.
