BP Daily Podcast: Effectively Wild Episode 373: Why the Manager Challenge System Might Be Broken

One thing that I find interesting about this system is that in baseball, both managers can run out onto the field to argue plays in order to give others a chance to view the replay and let them know whether to challenge the play. As a result, both teams have the option to stop the game without actually challenging. That's not the case in the NFL, where the offense alone controls the pace of the game (and even the offense is constrained by the playclock), and so I wonder whether how frequently that strategy will be employed. I suspect that it will result in longer delays than MLB expects.
