I'm pretty tough on Smart, but I need to acknowledge positives when I see them. What I've heard so far about the concentration of defense is great to hear. While we might not have many great individual defenders, we do have guys with defensive talent, but more importantly than individual talent on that end will be collective team defense, sharp rotations, talking, be in the right positions, knowing how to shade opponents, knowing your opponents, knowing as a team which shots you want your opponent to take and which shots you don't want to give up, etc..
We'll see how it pans out, but I did see one quote which I liked a lot from Smart, which stated we had the 6th best offense last year, so really no matter our system we'll score points, that's not the problem, defense was the problem and that's what we're concentrating on.
As long as it isn't guys reaching and going for steals too often, which I'm a little nervous about as that isn't sound fundamental defense and leads to defensive breakdowns and foul trouble, I'm hopeful on that end. Still could do better in the personnel department though with another big or two.
