The Titans are one of only three sides who are yet to earn a point in the first quarter this season, and Walker has highlighted the importance of his side starting as they mean to go on.
"Guys have to come in at the beginning of the game and say, look, this is all about us," said Walker, according to The Tennessean.
"We have to go out there and do what we can do. We have to fix that. We have to go out there and make a play. We have to go out there and execute and put points on the board."
This season will be Walker's second at the Titans, with the player originally being drafted by the San Francisco 49ers in 2006.
