Tennessee Titans defensive coordinator Jerry Gray has identified Andre Johnson and Matt Schaub as the Houston Texans' key players.
The Titans, who beat the Pittsburgh Steelers last week, face their AFC South rivals for this first time this season later today.
Gray told reporters: "Andre Johnson is Andre Johnson. You've got to know where he is on the field, and that's the thing they've done.
"They really made their team, everyone does a role, they all compete, they all contribute to what their role is and you can see it on film.
"[Schaub] can be one of the top quarterbacks in this league. He doesn't get the publicity that the other guys get, but you look at him and he throws all the right throws and makes the same amount of [stats], so, it starts with the quarterback."
Last season the Texans beat Tennessee in both of their meetings.
