There's a tinge of concern tainting the Golden State Warriors' pursuit of NBA history.
As the Dubs draw closer to 73 regular-season wins, they're also butting up against the mounting evidence linking fatigue and injury, much of which ESPN.com's Tom Haberstroh chronicled this past February. Nobody's certain what the toll will be for the Warriors, but with those studying the impact of player usage concluding health risks rise exponentially with increased minutes, it's reasonable to say the Warriors' approach will cost something.
And if the empirical studies don't persuade you, at least acknowledge the San Antonio Spurs' dramatically different approach to their nearly-as-great regular season.
