There's been a lot of change in the NFL as the 2021 season gets underway. The league added a 17th game to their regular-season schedule, permitted alternate uniforms for the 2022 season and gave players more freedom in picking their jersey numbers.
The league has relaxed its once-stringent rule on what numbers players can wear based on their position. Now skill position players can choose from a wider variety of numbers, including single digits. Many have taken advantage of the new rule, like Tennessee Titans wide receiver Julio Jones, Los Angeles Rams cornerback Jalen Ramsey and Dallas Cowboys linebacker Jaylon Smith.
