Marshall had an off year due to QB struggles, a lack of a running game due to aging running backs and an injured offensive line, and he missed two and a half games due to an injury.
Still though, he had 86 receptions(most in the AFC East), and 1,014 yards. Yeah he only had three touchdowns, but still those numbers are considered a bad year for him, most receivers in this league would call that a career year. Only five players in NFL history has had three straight 100 catch seasons, Marshall is one of them. Plus, he owns the record for most receptions in a game in NFL history and is a two time Pro Bowler. One off season where he still put up big numbers does not diminish that he is a special talent. He definitely deserves to be in the argument of being one of the top 5 receivers currently in the game.
