The Steelers went 4-1 in December and January, and it was in no small part thanks to the star wide receiver's output. In five games, the sixth-year player compiled 51 catches for 642 yards and five touchdowns.
Brown's 16 catches in a Dec. 20 win over the Broncos were tops in a single game all year -- if it weren't for the 17 catches he had against the Raiders just a month earlier. That Brown was able to nab those 16 balls for 189 yards and two scores against the league's most-revered defense speaks to why he's widely considered the best pass-catcher in the league.
Brown wasn't the only player to enjoy a big final month of 2015. Here are the rest of December's Players of the Month (which included January's Week 17 numbers as well):
Offensive:Redskins quarterback Kirk Cousins went on a tear on the way to leading Washington to their first NFC East title since 2012. The fourth-year quarterback threw for 15 touchdowns with only one interception for a 73.51 completion percentage, adding to his already league-leading total. The Redskins went 4-1 in the process.
Rookies of the Month:
Offense:Cardinals running back David Johnson emerged as a sleeper candidate for Offensive Rookie of the Year once he became the featured back following injuries to Chris Johnson and Andre Ellington. In a Week 15 win against the Eagles, Johnson had 187 yards rushing on 29 carries with three touchdowns. He had five total touchdowns in the five games.
