that seems unnecessarily complicated, the current format is already overwhelming for most newbies....
solid idea though, i must give you that, I can see how it would work, but it's quite complicated to put across to someone who knows nothing about the game. Or myself, who knew almost nothing about basketball (i'd only just started watching it - and was told about this by tough/SHAQ) before I joined this game lol. I would've been entirely lost.
Now that i do have a good grasp, I can see how it works, this is also a large bit of coding if i'd think about my little knowledge on programming to adjust. So while it's a good idea, it's not a plausible idea.
