OK, I get it now.
If you want to watch another team's game, you can select the "watch" option from the Scores & Schedule page. Easy enough.
If you are a manager, and you just want to watch your OWN game without interacting, do this:
1. Manage the game and select Start Game.
2. In the options screen, set all decisions to your bench coach.
3. Uncheck the "pause after each play" button at the top of the screen.
The whole game should play out now without your intervention.
Hope this helps.
