Raiders' Darren Waller: Nipping at Kelce's heels

Chiefs tight end Travis Kelce told NFL Films that Waller is "knocking at the door," adding that he can "feel [Waller] on my heels."

Kelce remains widely acknowledged as the cream of the crop at his position, but he knows Waller and 49ers tight end George Kittle aren't far behind. Waller even reached a new level over the final five weeks of last season, averaging 8.6 catches for 130.8 yards and 0.8 touchdowns on 11.0 targets per game. He'll again be the top receiving threat in Las Vegas, where John Brown, Henry Ruggs, Bryan Edwards and Hunter Renfrow top the depth chart at wide receiver.
