• If you manage the units - like with LoV - then it'll probably end up with the same amount of particupation as LoV.

• If YOU (the player) are one of the team units, then the whole passing the ball would have to lock players in place (no doubt to everyone's chagrin) each time a pass was made, and I have no idea how they'd implement the mechanics relating to intercepting a 'pass' (if it's even possible) or shooting at a goal given how objects interact in this game. I guess you could do something akin to Huttball in SWTOR and have the player move into the goal/cross a line, but that'd be odd considering it's meant to be Blitzball and fans of it will expect it to be as similar as possible.

It'd be a mess either way, as some things just don't translate well from single player games.
