I think what AA brings is completely sustainable. He is not going to score 15 or 20 on many nights, but he is a fierce defender and always busts his ass. If he is being relied on to demonstrate that hard defense and effort are the most valuable commodities then, I think he will continue to do that regardless of his scoring.
His intangibles are definitely sustainable - experience, leadership, effort.
His production, to which I was speaking, is not. Last 2 games: 21 points, 4 rebs, 2 ast on .500 fg and over 50% 3pt.
