But you can know the level of performance for a given athlete. We all knew Jordan would score thirty. And when he didn't every now and then, np,,, But if a three game stretch went by and MJ didn't hit for 25-30, he wasn't "normal". The same stands true for DD. Fans and viewers have seen her do some "wow moment" things. So when they don't see her have a wow moment all-game!!, in fact some un-wow moments,,,, they feel like the ones who caught Jordan in a funk.
Jordan felt it necessary to always show he was competing. He had fun. Made faces, but earned that right, by no one being able to accuse him of anything but full effort. This can, and should be gotten out of a gift like Diamond...And I am so vocal because I have handled some pretty hard to read, athletes. And I was able to get "their game" out of em.
Also consider, an old coaching adage, "You practice like you play" meaning, the effort they put into practice directly reflects in their game. Not the spectacular moments. . . The give-up's, the dropping of shoulders, tantrums, frustration outlets,,etc, they all happen in practice, if they happen in game.
That's what will turn DD... When practice-performance is "important", to both player and coach.
