To understand the legality of cut blocking, we must first define this technique. A cut block, also known as a chop block, occurs when an offensive lineman, typically a tackle or guard, blocks a defensive player below the waist while another offensive player, usually a running back or wide receiver, blocks the defender above the waist simultaneously. This strategic move is used to disrupt the defense's pursuit of the ball carrier.

Cut Block Rules Before 2019

Before the 2019 season, cut blocking was legal in the NFL as long as it was executed with proper technique. The primary rule was that the initial block below the waist had to be made by a player on the line of scrimmage, with the secondary block above the waist coming from a player who wasn't on the line.

However, this rule was open to interpretation and often led to confusion and inconsistency in officiating. Players and coaches often disagreed with the referee's calls, alleging that some blocks were cut blocks that should have been flagged, while others were incorrectly penalized.

Correlation Between Cut Blocks and Injuries

The controversy surrounding cut blocks intensified due to concerns about player safety. Throughout the 2010s, several high-profile injuries, including knee, ankle, and back injuries, could be traced back to cut blocks. Some players argued that these blocks were intended to take out defenders by targeting their knees and ankles.

In response to these injuries, the NFL Players Association (NFLPA) commissioned a study to assess the correlation between cut blocks and lower-leg injuries. The study, conducted by researchers from the NFLPA and.cartilage knee injuries compared to illegal cut blocks in which the defender was blocked above the knee or below the waist by two offensive players.

Injury Rates and the Decision to Ban Cut Blocks

The study found that the rate of cartilage knee injuries was more than three times higher when cut blocks were involved compared to other blocking techniques. These findings, among other injury data, played a significant role in the NFL competition committee's decision to ban cut blocks.

In March 2019, the NFL announced that cut blocks would be eliminated from the game, citing player safety as the primary reason for the rule change. Starting in the 2019 season, any chop or cut block would result in a 15-yard penalty, regardless of whether it was executed properly or not.

Cut Blocks After the 2019 Rule Change

With the ban on cut blocks, the NFL aimed to reduce lower-leg injuries and create a fairer playing field. However, the new rule has not been without its critics. Some coaches and players argue that the rule change has made it more difficult for smaller, quicker offensive linemen to effectively block larger, more powerful defenders.

Moreover, the rule change has led to an increase in the number of offensive holding penalties, as blockers struggle to adjust to the new restrictions. Some analysts and former players suggest that the ban on cut blocks has not significantly improved player safety, as defenders are now more susceptible to being cut when they are not expecting it due to the new rules.

Adaptations to the New Rules

Offensive strategies have evolved in response to the ban on cut blocks. Teams are now using more double-team blocks and employing additional players to help with pass protection. Some offenses have also begun to utilize more motion and shifting to create favorable matchups and misdirection.

Defensive strategies have also adapted to the rule change. Defenders are now focusing on maintaining proper gap integrity and working together to prevent big gains by the offense. Some coordinators have even begun employing more deliberate tactics to disrupt the offensive rhythm and force mistakes.

While the debate surrounding the legality and safety of cut blocks in the NFL continues, one thing is clear: the game's rules and strategies will continue to evolve as the league's competition committee and teams strive to create a fair, exciting, and most importantly, safe environment for players to compete. As the 2022 season approaches, fans can expect to see even more innovations and adjustments as the sport's top talents adapt to the ever-changing landscape of professional football.
