This 12 minute video by Fish Duck lays out Oregon's Inside Zone Read Option and Outside Zone Read Option. The "Inside Option" and "Outside Option" also make up the foundation of the Ohio State Read/Option offense. As everyone knows by now, Urban Meyer, Chip Kelly, and Dan Mullen were the architects of the Zone Read Spread Option tOSU uses.
Charles Fischer does a fantastic job of presenting this information in a clear and easily understood manner. Amaze your friends, piss off your enemies... And double your money back, if you don't love this video.
