In 2012, Mario Williams led the Bills with how many sacks?

In 2012, Mario Williams led the Bills with 10.5 sacks. He played all 16 regular-season games during his first season in Buffalo after signing as a major free-agent addition.

Williams recorded 46 total tackles, 10.5 sacks, and two forced fumbles. His strongest individual performance came against the Indianapolis Colts, when he recorded three sacks.

The 9.5 figure reflects an incomplete statistic from earlier in the season, rather than his final regular-season total. Buffalo finished the season 6–10 and missed the playoffs, but Williams remained the team’s leading sack producer.

His 10.5 sacks ranked among the notable defensive performances of his career and helped establish him as Buffalo’s primary pass-rushing threat in 2012.
