Yeah it’s depending on the zone there’s 5
4 qrts
4 palms
cvr 3match
cvr 6
cvr 9
4 qrts & cover 6 play the same but in cvr 6 it’s half of cv4 qrts and cover 2
cvr 4 palms - cvr 9 plays like palms to the palms side and cover 2 to the half’s side
Cvr 3 match has different variations like buzz which a safety replaces as a hook to curl and cvr 3 blitzs and the hooks are 3 recs, 3 recs will play to the strong side and take away the first route come from that side
but yes depending how far down the field a WR runs a specific zone will stick to him
