Here is a handy table. Adapted from The R4 Book authored by Coach Slack and Coach Maddox.
C = COVERAGE ATTACK = WHERE to THROW
Cover 0 attack DEEP on Rhythm
Cover 1 attack AWAY from deep single safety
Cover 2 attack the MIDDLE and STRONG SIDE
Cover 3 attack WEAK away from middle safety
Cover 4 attack the FLATS
Using this chart add what concepts you use to exploit each coverage.
