I just passed my exam to officiate football and have a schedule of games this fall. I'll be working 5-man and 4-man crews and expect to be on the sideline positions for much of my assignments. I'll also work some youth level games (probably some 3-man crews). If anyone here could point me to some video material (maybe even some online somewhere?) that I could view to help me learn, I would be most appreciative of the help.

Thanks in advance for your replies!
