50 slant vs trips with a TE

That is not too "earth shaking"! There are literally HUNDREDS of things the offense can do with SHIFTS/MOTIONSD/VARIOUS FORMATIONS - that is why adjustements must be FEW & SIMPLE (especially in HS) because they have to be made oin a SPLIT SECOND! I find that adjustments are just as difficult for the front 7 as the 4 deep in many instances!

This is what offenses hope to gain by "moving" people:
“MOVEMENT”

MOVEMENT IS VERY IMPORTANT TO OUR TOTAL OFFENSIVE SYSTEM.
THERE ARE SEVERAL REASONS FOR MOVEMENT IN OUR OFFENSE; AMONG
THE MOST PROMINENT REASONS ARE:

1. To create a personnel advantage by creating mis-matches on our Receivers or Backs.
2. To create a personnel advantage by effecting changes in run support and force responsibilities.
3. To create secondary movement in an effort to better enable our Quarterback to recognize coverage.
4. To get our personnel in better position to execute their given assignment.
5. To create problems for the defense in Man under coverages when attempting to hold or bump Receivers at the line of scrimmage.
6. To create an opportunity for indecision, confusion, and/or mis-alignment by the secondary.
7. To cause movement on the part of the Defense in an effort to realign their personnel with the coverage calls and changes and not allow them to set themselves and react to familiar offensive patterns. Make the Defense “play on the move”.
8. To force opponents to spend practice time and effort on adjusting to movement patterns rather than improving defensive skills and schemes.
9. To create a visual complexity to the defense, yet be able to run the same basic plays from a variety of looks.
