9. Antonio Brown, Pittsburgh Steelers
In the midst of the Steelers’ underwhelming 2013 season, Brown quietly established himself as one of the NFL’s most complete receivers, finishing second in the league in both catches (110) and receiving yards (1,499) with a career-high eight TDs. He’s entering his fifth season this year, but at age 25, still has plenty of time to hone his skills. (Gregory Shamus/Getty Photo)
