When it comes right down to it, something big enough to consume an entire city — a franchise's well-laid plans, a team's championship dream, the hopes of a million fans — stands fragile on porcelain legs. Everything is breakable, separated from collapse by dumb luck or whatever mood fate happens to be in. The difference between a thoroughbred racing to glory or writhing in the dirt can be the snap of one astonishingly frail limb. Every team is a locomotive running on glass rails. Nobody feels sorry for the Heat. Start there. Outside of Miami's fans no one is lamenting that the favorites to win the NBA title suddenly are without Chris Bosh "indefinitely" — probably at least for the rest of this second-round playoff series with Indiana continuing with Game 2 on Tuesday night.
