yeah, not to mention the avada kedavra spell...,insta kill. Although, i'm sure a well placed throw by an experienced jedi could cut down several wizards at once. Just as the Jedi have nothing to defend against spells, the wizards have nothing to defend against force powers. The Jedi or Sith still have a chance to win this but it would take a flawless blitzkrieg of force push and saber throws. I'm also not sure if the Jedi or Sith would be able to dodge spells with their force speed. I know i have seen the wizards in the Potter movies miss with their spell casting.
