@markheisler on TwitterThe torch passeth.If Tim Duncan has played his last game, he went out on an unexpected performance like Kobe Bryant's.Duncan only scored 19 points but expectations aren't what they used to be at 40 after scoring 17 -- total -- in Games 1-5 against OKC.If the Spurs' 4-2 loss isn't Duncan's farewell -- I'd guess it wasn't -- the torch is passing anyway from the Spurs and Lakers who won 10 of the last 16 titles (five apiece) to whoever comes next.
