You already knew about the live updates from Inside MD Sports via Twitter, but NBE Basketball Report is rolling them out too (not via Twitter). Definitely worth checking out. FWIW, Tobias Harris is #3 in points and Terrence Jones is #2 in rebounds.
Inside MD Sports, the ESPN version of TurtleSportsReport or Terrapin Times, has free, live updates from Peach Jam, an AAU tournament in (where else?) Georgia. These updates come via (what else?) Twitter.
