I think it would be alot easier to implement to add "alternate tactics" to the game. So you advise your coach to "swith to plan B" if "opponent does this or that".
For example:
Starting Offensive Tactics: Motion
Alternate Tactic: Look Inside
Trigger: if opponent plays 3-2 Zone, switch to Alternate Tactic at the beginning of the next quarter (next half)
Starting Defense: Inside Box Plus 1
Alternate Tactic: Man to Man
Trigger: if opponent playes Run and Gun, switch to Alternate Tactic at the beginning of the next quarter (next half)
If you limit the choices, options wouldnt blow up the game, yet it would become more realistic, as coaches usually see if something doesn´t work out fine and tend to aplly some changes.
In addition, one might ponder letting a team choose a tactic / game scheme for every half or every quarter, attacking the other team with different schemes and trying to take advantage of strong bench players.
Actually Pressing might become a viable option if you only use it for one quarter to get the opponents set up screwed up.
