Underlying principles for the use of multiple formations

"One of the key elements in this pass offense is its adaptability to multiple formations and personal groupings" (Gonzalez 20). Most college and high school football teams tend to have four wide receivers on almost every play and the use of multiple groupings can help an offense create a more advantageous match ups. From personal experience I have seen this too as I have watched college football and sometimes high school football. In the diagram below it shows space created for the Z receiver in a pass defense.

Multiple formations can also allow a team to take advantage of their best players. Certain formations can make a the front and run support predictable which makes the pass support more predictable. In this other diagram below it shows the wing set forces the defense to commit the strong safety to a force position, this also results in a soft corner technique.

To conclude the use of multiple formations helps substantially and to some degree standardize the defensive structures being faced. "At the high school and small college levels, many teams would prefer to leave their starting unit in the game, as opposed to the substitution defenses seen in larger college and professional ranks" (Gonzalez 21). From this it shows that high school and small college football teams don't use many different formations and keep their starting units in. Have you ever watched high school or small college football teams and then professional football? If yes then could you tell the difference in the formations?
