when this team is locked in they defend absurdly well. It reminds me of cogs spinning together and it looks effortless. As offenses move the ball around our rotations are flawless and guys are never late or out of position. This is why we have forced a lot of TO's and why we do a good job on defensive boards IMO.
I also think that is something that really only comes with good athleticism but more importantly playing together in a system for a long time and getting tons of minutes together.
