The Dynamic Demo

From The Rogue's Baseball Index

The Dynamic Demo is that feature of the MLB Network and Baseball Tonight, in which former players loiter with broadcasters on an oddly undersized simulated baseball diamond. They demonstrate the little things that happen in a game, like turning a double play or putting down a sac bunt. They also do a lot of patting of the gloves while someone else explains, for example, how to lead off of first base.

The Dynamic Demo has its roots in a similar practice on NFL Sunday broadcasts. Unique to the latest incarnation is that the MLB Network guys often change into actual workout gear, and they hit wiffle balls around the studio. Also, Terry Bradshaw never dunked a perfectly good football into a bucket of water, then smeared it with shaving cream and hung it from the wall.
