In Navy’s huge bowl win versus Virginia (49-7), Navy was in a Flexed formation 99% of the time.
This means they brought the Receiver in two yards from the Tackle.
63% of the time versus Virginia, Navy was in Double Flex:
Only 37% of time versus Virginia, Navy split out a single Receiver.
Only 1% of the time versus Virginia, Navy split out two Receivers.
In 2017 Navy’s #1 formation was Double Flex. No other formation was close. The offense is certainly evolving.
