Brown, a second-year player from Central Michigan, became the team's single-season leader in all-purpose yardarge with 2,048.
Brown is the first Steelers player to win the Team MVP award in his second year of play since Rod Woodson in 1988.
Going into Week 17, Brown has 1,018 receiving yards, 664 punt return yards (with one touchdown) and 325 kick return yards to go along with 41 rushing yards.
LB James Harrison was voted Team MVP in 2007 and 2008. The award went to Ben Roethlisberger in 2009 and Troy Polamalu in 2010.
Brown was a sixth-round draft pick in 2010, and saw limited time in the regular season, but did come up with two big catches in the playoffs. His 58-yard catch against Baltimore led to the game-winning touchdown that put the Steelers in the AFC Championship game.
Against the Jets, Roethlisberger hit him for 14 yards on 3rd-and-6 to seal the 24-19 victory.
Brown has made plenty of highlight plays this season, and has taken over as the team's most targeted receiver. He was named to the AFC Pro Bowl team as a kick returner.
