The NFL released three rules updates yesterday, right after I finished writing up my thoughts about the changes from the day before. You can see my analysis of the rule changes from yesterday here. Like the first set of rule changes, there are two minor changes and one big one.
First the minor changes. Replay can now review if the play clock expired before a snap. Replay can also now review down by contact or out of bounds before a pass was thrown. These are two great changes.
I have written previously that replay is of use almost anytime it allows for an additional perspective on the play, and it is almost never useful when it uses additional judgement on the play.
