Well this is kind of dumb: the argument here is that Coach K is risking his legacy by coaching the Olympics again. Hardly.
While it's clear that there are no guarantees of victory - Spain and Lithuania have given the U.S. fits, and other teams are rising - the U.S. formula of unity and defensive intensity paired with overwhelming athleticism has proven very hard to overcome.
And even if the Americans lose, our entire international system has been overhauled and vastly improved. That's the legacy.
