Look, I am going to agree that one of the things that THEY should have practiced is back and forth give and take with Bush - and not the canned speach stuff. Bush does need to keep short notes as Kerry talks about factual and other errors that he needs to address. Kerry's MO is pretty well established by this point and so Bush's preparation team should have done better with him. Everyone knows it is not his strong point, and his team should have been practicing with him starting about 2 years ago. A little bit of practice every other week would have gone a long long way.
Of course, Bush is a busy President and probably doesn't have time for a lot of useless activities like this.
