Buffalo Bills' Mario Williams turns 31 years old today

On March 15, 2012 the Bills announced the signing of Mario Williams, then a 27-year-old former No. 1 overall pick. Today, Williams turns 31 years old. How have the last four years turned out?

In those four years, Williams recorded 43 sacks. That's the sixth-best total in that time, trailing only J.J. Watt, Justin Houston, Von Miller, Robert Quinn, and Elvis Dumervil. It also puts him at fifth on the Bills' all-time sack leader list. Bruce Smith, Aaron Schobel, Phil Hansen, and Cornelius Bennett are the people head of him on that list. They all have at least twice as many games played for the Bills. He's made the Pro Bowl twice as a Bill, and was a first team All-Pro in 2014. He and Marcell Dareus were the Bills' first All-Pros since Brian Moorman in 2006.

Williams has been a controversial figure as a Bill. No matter what fans' opinions of him are today, however, he'll be in the Bills' record books for a while to come. Happy birthday, Mario!
