And things just got a little more difficult. The Mavs have just tasted defeat for the first time in the postseason, losing Game One of their highly-anticipated series against the Spurs, 87-85. Tim Duncan, creaky old man with the bum ankle, went for 31 points and 13 boards. Jerry Stackhouse led the Mavs with 24, as Dirk Nowitzki was held to 20 points on 8-of-20 shooting. No word on what the loss did to the size of Mark Cuban's penis.
