Help me test this

[squadron supreme]

I'm playing on all-american with the only slider change being cpu interceptions lowered to 20. I'm playing a play now game against Miami and they are playing cover 2 as usual but the safties are playing looser zone. I noticed this because I played them twice in dynasty with all regular settings and the safties played an aggressive tight zone. Now they seem to be playing a more conservative or balanced zone more consistently. Again I maybe halucinating but someone test this out with other teams in a play now game to see if this really makes a difference.
