None of the basketball mods are that good for anything. A basketball mod thats also allows many people to play at one time for one side would be amazing!

You know that online works only for 2 ppl at the same time, dont you? There are some basket mods where you can coop with the other player if thats what you are looking for

Have you tried the God Team basketball mods yet?

gtdunkcontest.tbm and gtfastbreak.tbm (Pretty sure they're in your modfolder by default)
