HoDo,
I see your point, but I have always thought that theory was a little over-rated. All teams understand the basic philosophy that other teams use in their offenses and defenses. On top of that, coaches watch tons of film and pick up tendencies of the other teams. Luke might be able to give them one or two bits of info, but I don't know how much it would matter. As close as Saints/Falcons games have been lately, every little bit helps, but I'm not sure what he could tell them that they don't already know.
