at the top of the team game planning screen where it shows some details about your upcoming opponent, it displays what type of offense and defense they run,,,does that section change immediately based on what defense the team has set on their team game planning page? basically i am asking because if i play mostly a 3-2 zone, but then i want to switch it up to a 2-3 zone against an opponent...if i do that too early in the day, will they be more likely to see that i changed? so should i wait until later that night to game plan? kinda silly question, i know...but just curious?

yes, it reflects the defense as set at that moment, so setting it too early will tip your hand if you run a zone or combo defense and vary it based on opponent.
