The NFL is always considering rule changes that will improve the game (from their perspective). In recent years, they moved kickoffs up and extra points back and have made sweeping changes to the rulebook.This has happened a lot more frequently as more studies are completed. New information comes to light or things are revealed that need to be changed.This year, the NFL decided to look more intently at illegal contact fouls. Officials will be looking closer at this because there was apparently a worrisome drop in those penalty calls last season.Bleacher Report@BleacherReportThe NFL has asked officials to focus on illegal contact fouls after seeing a big drop last season, per @SeifertESPN96160The NFL has asked officials to focus on illegal contact fouls after seeing a big drop last season, per @SeifertESPN https://t.co/8eyYZls0acThis has left NFL fans frustrated with the league.

According to ESPN's Kevin Seifert:"Illegal contact refers to prohibited contact by a defender when the quarterback still has the ball and remains in the pocket. It is a five-yard penalty and results in an automatic first down."Many rule changes that the league institutes are to protect its players. It's why recent rule changes penalize players for leading with their head when hitting another player.Denver Broncos v Arizona CardinalsThe league is most concerned with protecting quarterbacks, which is why this rule is in place and why defenders will be more penalized for it this year.This most often refers to contact to the head and neck area, which is more proof that the NFL is, at least, attempting to limit head injuries.It's a fairly subjective call because it comes down to what referees deem as "prohibited contact." It's separate from roughing the passer, which also makes it a little more difficult to call.
