I was thinking about how they could potentially make Blitzball and think that the idea is to make it so passing and shooting can be done whenever to make it less stop-start like the original. They could make it so that your character throws/shoots in the direction your character is facing and can look around with snap-back to centre. They could make blocking able to be done like a real sport by getting in the way. The only time when the game needs to pause during the game is when someone collides with someone to do the tackling component of the game.

These are some ideas I've had thinking about it and there's obviously some anti-cheese mechanics like preventing anyone from coming in x yalms from the goal to prevent people from making it impossible to score by body-blocking the whole goal.
