Since the start of last season, Brown ranks sixth in the league with 76.6 percent of his receptions resulting in first downs behind Malcom Floyd, Vincent Jackson, Calvin Johnson, Rob Gronkowski and Roddy White.
Last season, Brown piled up 2,211 all-purpose yards to break Barry Foster's franchise single-season record.
He became the first player in NFL history to have at least 1,000 receiving yards and 1,000 kick return yards with 1,108 receiving yards and 1,062 return yards.
"He's definitely one of the top receivers in the league, I think," Ravens cornerback Cary Williams said. "He's very versatile. He can run any route. He can run inside, he can run outside. He has great body control. He has great hands and ability to run after the catch."
