Discipline and fundamentals. Players and talent are there (although room for improvement).
I've been rewatching games from this season. The glaring fundamentals we are weak and lacking in include:
Boxing out
Setting screens
Staying in front of our man on defense
Those are basic things that our players are embarrassingly bad at. Especially for a professional team. If we could do those things consistently, we would easily be in the 8th spot right now, potentially higher.
While I agree to some extent in general, I don't like generalizing. It's too easy to throw everyone in the same pot. People think that setting a screen should be easy, but actually, it takes two to make it work. It's all about timing. There are times when a perfect screen is being set, but the user gets there too early, too late, or doesn't use it properly. Most of all, I think timing is the main factor, and that comes from playing together, which has been a problem for the Kings.
Then you have young players that were stars in high school and college, that weren't asked to set screens very often. That said, there are players like Len and Holmes, that do box out and do set good screens, and know when to roll to the basket. My biggest complaint is on the defensive side of the ball. It's easy to say that a player should be able to keep his man in front of him in space, but how many players in the NBA can keep Fox in front of them. It's team defense that wins games.
How many times does the help come too late when someone on the perimeter is beat, and it's going to happen. How do you defend, when you have a player that totally disregards where his man is. Something Buddy is prone to do over and over again. If one of the five players on the floor isn't attempting to do his job, it doesn't matter what the other four do. So I'm not disagreeing with you. I just don't like lumping everyone together. There needs to be more individual accountability.
