Arthur Moats is an American football outside linebacker for the Pittsburgh Steelers of the National Football League (NFL). He was drafted by the Buffalo Bills in the sixth round of the 2010 NFL Draft. Moats played college football at James Madison, where he was team captain. He is well known for delivering the hit on Minnesota Vikings quarterback Brett Favre that ended Favre's streak of consecutive starts the following week at 297. Moats finished his career at James Madison University with 208 tackles. He played in all of his team's games as a true freshman. He started only 5 games as a sophomore, but became a full-time starter for his junior and senior years. Moats won the 2009 Buck Buchanan Award as the top FCS defensive player.

Moats was drafted by the Buffalo Bills in the sixth round, 178th overall, in the 2010 NFL Draft. He is the only Buck Buchanan Award winner to be drafted by the Bills. In the Bills 3-4 defensive scheme, he moved from defensive end to inside linebacker, which is an unusual position change considering most defensive ends move to outside linebacker in 3-4 defensive schemes. After several weeks of failing to generate a consistent pass rush, Bills head coach Chan Gailey decided to move Moats to his more natural position of outside linebacker to utilize his pass rushing skill set.

In December 2013, Moats was named the team's Walter Payton Man of the Year for 2013. Moats earned this honor through his work with the United Way of Buffalo and Erie County and other local groups. Moats was also named the Bills Ed Block Courage Award recipient. He earned this honor by overcoming adversity from an injury and exemplifying courage both on and off the field. He also conducts numerous school visits and takes part in the NFL Play 60 initiative.

On March 9, 2015, the Pittsburgh Steelers signed Moats to a three-year, $7.50 million contract with a signing bonus of $1.90 million. Moats began 2015 as the left outside linebacker ahead of rookie Bud Dupree. In the second game of the season, he made three combined tackles and was credited with half a sack after taking down San Francisco 49er's quarterback Colin Kaepernick while helping his team route the 49ers 43-18. On January 3, 3016, Moats racked up a season-high six solo tackles and sacked Cleveland Brown's quarterback Austin Davis, helping the Steeler's win 28-12. On January 9, 2016, he collected five combined tackles as the Steeler's defeated the Cincinnati Bengals 18-16 in an AFC Wild-card mathcup.
Moats finished the 2015 season with 35 combined tackles, four sacks, and two pass deflections and appeared in all 16 games and started 11.
