Aidan Hutchinson from the Lions with historic pace

The sack is somehow still an underrated skill among some NFL fans these days.

The NFL is rapidly growing in popularity around the world, largely due to high-profile offenses. Offensive records appear to be being chased and broken more often because the league has expanded the rules and imposed harsher penalties on defense. Some fans love the offensive explosions of their fantasy football players, touchdowns and colorful scores from their favorite teams, but a great defense can provide the same excitement.

The NFL sack leader heading into Week 4 is Detroit Lions defensive end Aidan Hutchinson. He leads the NFL with 6 1/2 sacks heading into Detroit's Week 4 showdown against the Seattle Seahawks on “Monday Night Football.”
