You could maybe do it like that, but he's talking about a standard pro ranked type match with two player on one team and one player on the other. Unless you're organising it properly and you know your opponent as well as your team mate in which case, like you say you can make an online teamplay game although I'm not sure if you can make private ones of those, I sold the game way back a few months ago. I'm pretty sure that you can only have one ANY player at a time as well, as it counts as if one person chooses it then it's greyed out for the other person and non selectable. Meaning one player is only in control of one man and the other player is in control of everyone else.
