It didn't take long for Davis to make his mark when he returned from a five-game injury absence last month.

In his first game back in the lineup, Davis sprinted down the right sideline and went high in the air to snare a 23-yard, back-shoulder pass, one that would lead to a Titans touchdown against Baltimore.

He's posted 13 of his 20 catches in the four games since returning to the lineup, and the fact that Mariota continues to look for him – Davis' 6.5 targets per game this season are just behind Walker (7.0) and Rishard Matthews (6.8) – is a promising sign.

"He has all the confidence in the world in me, he trusts me," Davis said of Mariota. "He puts the ball in the right spot and definitely makes my job easier. I've got to make him look good."

Teammates and coaches alike say they have seen Davis continue to make progress, despite the occasional setbacks that come with being a rookie.

"It looks to me like he's come a little further along in the route-running and that he's more into football shape now," Robiskie said. "You see him putting his foot on the ground, and planting and cutting and doing things … He's running fast, and he's getting in and out of things fast."

Added Walker: "He's improved his ability to run routes and attack the ball. That shows he's going to be a force to be reckoned with, once he gets his legs under him and really understands the concepts of what they want from him."

Davis believes he's making strides as well, even as he reminds himself the growth process does take time.

"I want to make plays and I want to do whatever I can to put my team in the best position to win," Davis said. "I know it's not all going to happen right away. It takes a lot of work and a lot of adjustment to the speed of this game. So I have to stay patient."
