I agree with you.  Dink and Dunk offense has to go 10 to 15 plays to get in scoring position.  And the offense has to be perfect in those 10 to 15 plays.  What I mean is if the offense commits a penalty or two (or a fumbled snap), it puts the offense in 3rd and long situation.  In today's NFL, you cannot consistently have long time consuming drives.  You have to have several big plays (either on ground or air) to move the chains.  Chunk Yardage.
