Introduction
When Sonny Dykes came to Cal, he talked a good deal about his offensive philosophy. He said that there are a bunch of different ways to fool people. Pre-snap, you can use formations, motions, and shifts to get the defense out of their alignments. You can also use trick plays and post-snap misdirection to spring guys open. A third option is to use tempo to keep the defense from subbing and getting new calls in. This last option is, obviously, the approach favored by Dykes and the Air Raid guys.
New OC Beau Baldwin hasn't made similarly explicit claims about his approach to offense.
