Last year he played in a hybrid system that allowed him to move around and line up in various spots to create mismatches and/or get lost. He lines up beside Roquan Smith and Patrick Queen or with them behind him, and beside or behind Madubuke.
There are 4 probowlers on the Ravens defense, and none of them are Clowney.
Clowney NEVER saw a double team in Baltimore, while Derrick Brown is a pretty solid starter at DT, no one else on that defense is worth mentioning. Clowney will be double teamed every play, and I doubt he gets 5 sacks this season.
