the other day during practice, an interesting pattern started to arise.  the pm would give a speech, the LO did her job and rebutted and proceeded to argue.  The DPM did likewise, but the DLO came up and did the rebuts and argued, but didn't really go back and rebuild the LO's case.  And it became apparent, we were doing 6 individual speeches, and not one cohesive extended debate.  the LO would rebut and argue, the DPM would rebut the previous arguments and then, proceed to new arguments without regard to the LO's rebuttals on the PM.  It's important to remind your debaters to stay focused on the global aspect of the debate as opposed to the micro, where it's all about the previous speaker.
