In the link are several videos about the ASU/UCLA offense. They are relatively short, under 10 mins. Mazzone is great and if you watch the videos you'll see how most of the offense is set up around one play: inside zone. From then on out, it is mostly about "protecting" inside zone and then "protecting" the plays that protect inside zone. If the end crashes down on inside zone, the QB pulls. Mazzone doesn't want a running QB/to get his QB hit, so he'll usually give the QB a WR screen option. Go inside to cover the back, QB throws outside. Go outside and inside and the red sea parts for QB run. Come up to hard to cover WR screens and they slip the blocks and go deep. This is the direction many college offenses are going: go FAST and get the ball snapped before they can get set up, keep the offense extremely simple, spread the field (in this case to run, but in all cases to spread defenders out and be able to read them easier), and make all your plays work together (to "protect" other plays). I thought this might lend some insight as to how a "system" works and what a draft prospect's offense was like.
