In the last several seasons, Pittsburgh Steelers All-Pro wide receiver Antonio Brown has emerged as arguably the best player at his position in the NFL.

Ahead of the pivotal matchup between the New England Patriots and Steelers in Week 15, Pro Bowl cornerback Malcolm divulged what exactly has made Brown such an elite wide receiver in the NFL, according to Mike Reiss of ESPN.

Asked how Brown challenges him, Butler said, “He challenges everyone. Everybody will have the opportunity to be on him, not just me. You just have to play good football.”

As for what makes the 5-foot-10, 181-pound Brown so effective, Butler said, “Everything. Speed. Heart. Strength. Quickness. All of that.”

Brown is the complete package wideout that has shown the ability to greatly impact the game on a daily basis. This is evident by him becoming the most productive wide receiver over the last five years as he holds the league record for the most receptions (580), and receiving yards (7,824) over that span.

He also has the NFL mark for most games with at least 10 receptions in a player's first eight seasons with 19. Meanwhile, currently being just one reception shy of becoming the only player to post five straight campaigns with at least 100 catches and 1,250 receiving yards.

The 29-year-old has continued to show each week that he has all the physical tools and ability at the position to possibly test Hall of Famer Jerry Rice done the line for many of his prestigious records. This makes Butler's matchup against him on Sunday a potentially huge factor in determining how the game will play out.
