Offensive interference and defensive pass interference, in addition to non-calls are now reviewable. This will have a major implication on the game as we know it in the 2019 season.
Now coaches can challenge any passing play to stop the game and ask for a review. Plays such as the Hail Mary can undoubtedly be more questioned, whether they have a tremendous affect on the end of the game or not. In this sense, quarterbacks will be affected especially if they can throw the ball deep.
Overall, this was a progressive move made by the league in order to adjust for the improvements in technology that are available, as well as address the issue that arose from the ending of the NFC championship game of last season. If that play were to have been reviewed the Super Bowl competitors would have been different.
