I think it would be crazy for mentioning anything about 3D matches, I know it is very hard to achieve, and a lot of things should be changed, to be able to have 3D matches.
But is it possible in BB?
It would be fascinating to know what our players exactly do in a match, to do further analysis. ( For me, I just watch the results and statistics only, but I would not know how tough my players defend, how they make a turnover, or their shot decision making)
