The purpose of this thread is to explain basketball concepts, plays, formations, etc. in an easily understandable way that will hopefully lead to people enjoying the game on a deeper level. All the b-ball nuts here are welcome to contribute. If you want anything explained, please let me know and I'll be happy to do so to the best of my abilities.

Today's Concept: Blue the Screen
To "Blue the Screen" is to defend the pick and roll in a certain manner. Basically, what it does is prevent the ball handler from using the screen by overplaying in the direction of the player who is setting the screen, making it very difficult to run the pick and roll. But it can be beaten with the right technique. At 2:13 of this video, you see an example of the Denver Nuggets "bluing" a screen. (this video is a good lesson in pick & roll defense in general, btw)
What does it mean to "Blue" the Screen?
At 2:13, Chauncey Billups is "laying" on the screener, (overplaying in that direction) because he's recognized where it's coming from, and George Karl is a coach that really likes to do this. This requires the big man that's helping out to not necessarily guard the ball-handler, but to contain him long enough to prevent penetration and ruin the pick and roll. This is an effective concept for the Nuggets because their big men (Nene, Martin, Anderson) are MUCH quicker than most teams, so they're able to contain a PG or SG longer than most teams can. Nene does this very well at the 2:13 mark
If a team can effectively blue a screen, the only option that's available for the offense is a contested jump shot or trying something else when there's 12 seconds or less on the shot clock. Either option is a victory for the defense.
How do you attack a team that's bluing the screen?
There are a couple of different ways:
Crossover and split (Selling the baseline)
Your guard should always be quicker than the big that's guarding him, even if it's a quick big like Nene. The "Crossover & split" concept is to pretend like the guard trying to go baseline and around the big man that's guarding him. Once he gets the big man going in that direction, he goes back toward the middle, effectively "splitting" the double team. This creates a 4-on-3 situation that works in the offenses' favor, and it's in the middle of the floor, giving the offensive player a lot of options. Controlling the middle is a huge advantage.
The defender isn't bluing the screen in this video, nor does the ball handler sell to the baseline but it's a cool explanation by Manu and the concept is pretty much the same. I think you can probably picture this in the blued screen scenario.
A blued screen is somewhat of a double team. You're overplaying the ball-handler with the big man, but the guard is still on him as well. If the ball-handler backs up a bit, he draws the attention of both defenders. If the man who's setting the screen can get in the position to catch a pass, it sets the offense up for a 4-on-3 scenario.
Here's an example @ 7:20 (Kobe's the best in the league at this by far, btw)
There are a couple of other options, but I think that's good for now. Here's a solid article by an assistant coach from the Nets if you want to get into more of the meat & potatoes.
