Yeah I expect the rules to be pretty different team by team:
- How much more aggressive are you with the first challenge than the second?
- Do you let guys challenge any pitch, or only pitches that end a PA?
- Do you let guys challenge during any PA, or only those at a proper level of leverage?
- For the prior two questions, how egregious does a call have to be to throw the rules out the window?
- How much different are the rules for a guy like Bregman vs. a guy like PCA?
- On defense do you let pitchers challenge at all, or just catchers?
I think every team will be different, but I expect the league will be far too conservative for at least a few months, maybe a few years.
