The 2019 NFL preseason got underway Thursday night with the annual Hall of Fame game and now 64 more exhibition games will follow over the course of the next four weeks. During these next four weeks it will certainly be interesting to watch the officiating and especially when it comes to new rule changes and points of emphasis.
While offensive and defensive pass interference penalties now being challengeable is certainly one key rule change that will be worth monitoring closely throughout the rest of the preseason, there are plenty of other of rules and penalties that are also expected to be heavily emphasized over the course of the next month so that teams will know what to expect during the regular season.
