The NFL released its official rule book for the 2017 season, and it includes a list of the major changes. You’re probably well aware of the changes to overtime and the ban on leaping over the line to block field goals, but one small change likely flew under your radar, and it’s not a fun one:

ARTICLE 3. INTENTIONAL FOULS TO MANIPULATE GAME CLOCK A team may not commit multiple fouls during the same down in an attempt to manipulate the game clock. Penalty: For multiple fouls to run off time from the game clock: Loss of 15 yards, and the game clock will be reset to where it was at the snap. After the penalty is enforced, the game clock will start on the next snap.

In other words, ingenious strategies like the one the Ravens used to finish off a game against the Bengals last season are no longer possible.

The 49ers used a similar strategy to prevent the Saints from taking a shot at the end zone before the half.

Look, I get why the NFL would want to stamp these plays out (something about sportsmanship) but this is a lame change. Football is a great sport, in part, because of the strategic battle between coaches. Coaches should be rewarded for coming up with new strategies that fall within the guidelines laid out by the rulebook.
