The Indianapolis Star has a good article on how the Pacers use video as a critical tool in their pre-game preparations.
The Pacers have a large video crew that tapes virtually every move of every player and break things down in minute detail for review. Some players, like Jermaine O'Neal and Al Harrington, even take a tape home after every game. The whole team views a special highlight pakage of the opposing team before every game. An interesting read.
