Good Point.
This happens enough, albeit only twice or so each season, that it merits a regular pre-game mention. Especially with a three-man crew.
The video doesn't, of course, mention everything involving a jump ball scenerio, but it is a good, basic learning tool for new officials.
Another unmentioned scenerio: held ball between two opponents after the jump ball before team control is established results in jump ball between those two players at the center jump circle. That's also happened enough to merit pre-game mention.
Shucks, there's some veterans who could learn from it, too.
