While Scioscia doesn't know exactly how the latest proposal -- which will be voted on in November and focuses on a "challenge" system -- will play out, he is also unsure of what will happen to the pace of the game.
It has been suggested that replay may speed up the game because managers won't have to argue calls, they will simply "challenge" them.
However, that may not necessarily be the case.
"There are going to be some plays where you have to get some understanding on what they saw and what you're challenging," Scioscia said. "If it's going to go quicker, I don't know."
On-field arguments may decrease, but Scioscia explained that on a play where the first baseman bobbles the ball, the manager will still likely need to talk to the umpire to make it clear that he is challenging the bobble as opposed to whether the first baseman's foot was on the bag.
