re: Why doesn't every CFB team run the Air raid/Spread, etc. ?

I've posted it before, but the "problem" with these offenses is also why they work. That is the uptempo style of play allows them to put points up quickly.

However, it also gets them off the field fast regardless if its a successful possession or not.

For example, if Team A can score in 30 seconds and Team B scores every time team A does while taking 7 minutes, what difference does it make?

Now, when Team A goes 3 and out in 25 seconds like Oregon does, and Team B takes 2 minutes to 3 and out, or any variation of downs and TOP, there is HUGE difference over the course of the game until it reaches a tipping point. Points pile up late for the ball possession team.
