There are very few sure things anywhere, but it seems as though there are two in the NBA: Kemba Walker losing to LeBron James and the Atlanta Hawks losing in San Antonio. Walker is 0-28 in his career against James-led teams, while the Hawks haven’t won against the Spurs in their home arena since 1997. The latter streak looked as if it could fall on Tuesday night, but San Antonio was able to rally back and deliver a 117-111 win to keep things going for a 21st straight time against the lowly Hawks.
