Charlotte Bobcats coach Paul Silas floated the idea last week of playing point guards D.J. Augustin and Kemba Walker at the same time once they got comfortable with each other, even though it might put his team at a big size disadvantage. Apparently they're comfortable. When crunch time arrived Monday night both were on the floor. Augustin scored 19 points, Walker added 13, including two free throws with 9.9 seconds remaining, as the Bobcats erased a 14-point second half deficit to beat the Milwaukee Bucks 96-95 in their season opener.
