Speaking at a Clinic

Coaches, I am speaking about defending the spread offense at a clinic in February. I will be spending 1 hour talking about defending the spread running game and another hour about defending the spread passing game. With such broad topics I have plenty that I can talk about for those 2 hours. My goal is that everyone who attends will gain something from the talk no matter which base defense they run. Obviously I can talk X's and O's, game-planning, technique, and other things. I wanted to ask you all to throw out ideas or topics that you would hope to hear about if you were attending these sessions. Thanks for your help.
