A look at the Pittsburgh Steelers who were "up" and those who were "down" in the 2015 season.
UP
Antonio Brown: He was the team's MVP for this ridiculous stat line -- 136 catches, 1,834 yards, 10 receiving touchdowns. It was one of the best single-season receiver performances of all time. And to think he put up these numbers without Ben Roethlisberger for four games.
DeAngelo Williams: He had one of the best seasons of his 10-year career. Williams led all Steelers playmakers with 11 offensive touchdowns and would have been well over 1,300 yards rushing had he been the starter all year.
