Many of the "scat backs" in the modern era produce more total yards and touchdowns than their ancestor "power backs" by breaking off big plays on outside runs and receptions. The spread offense and the hurry-up offense change the halfback's role but create more opportunity for these plays. The spread, the hurry-up, and the pro-style offenses dominate American football but the "smash-mouth" style of play is far from extinct. A power-running scheme is often utilized to counter an effective Spread attack, as it allows a team to control the clock and keep the ball out of the opposing offense's control. This strategy is utilized in NFL, college, and all other forms of American football. The need for "power backs" is very prevalent, alongside the need for "scat backs", and anything in between.
