If DMI had absolutely no point, why is it there?
I like to determine some players by game shape. If someone has bad game shape, I usually put them on the backups. It is how they did in practice, and will make them perform better on the court.
However, Game Shape is an indication of how sharp the player looked in practice and therefore how well he will be expected to play in a game; it is not an indicator of how effective his training sessions were.
