NASHVILLE, Tenn. – Dorial Green-Beckham wants to succeed in the NFL, and the Titans know it.

On the first day of training camp, the second-year receiver stood at his locker and said he's determined not to fail. Green-Beckham has his reasons.

Here's one:

"I just don't want to let our organization down,'' Green-Beckham said. "I want to do things the right way. And I want them to know I am dedicated to help this team win."

On Monday night, however, Titans coach Mike Mularkey told reporters Green-Beckham needs to do more. It came following the team's scrimmage at Nissan Stadium, just over a week into training camp.

"Nobody wants to please and do good for this team more than he does," Mularkey said of Green-Beckham. "And I know that. He's just got to find a way to come out every day and make the plays that are called his way. That's got to be every day, and it just hasn't been that way.

"I'd say (he's) inconsistent still. It's bad day, good day, same thing since the very first day."

The Titans are counting on Green-Beckham, who finished last season with 32 catches for 549 yards and four touchdowns, in 2016. As a rookie, Green-Beckham finished the year with more catches, yards and touchdowns than six of the seven receivers selected in front of him, with the lone exception being Oakland's Amari Cooper, the fourth overall pick of the draft.

Down the stretch in 2015, Green-Beckham became one of the go-to receivers for the Titans. He led all NFL receivers in percentage of catches that resulted in a first down (93.8%). Of Green-Beckham's 32 catches, 30 resulted in a first down. Tampa Bay's Mike Evans finished second on the list (85.1%). Green-Beckham racked up 445 receiving yards from Week 9-Week 17, starting with his 77-yard performance against the Saints.

But he's been running deeper in the rotation in training camp. Rookie Tajae Sharpe has worked with the first team, ahead of Green-Beckham.

"Spending extra time, that's doing things when nobody is watching," Mularkey said when asked what Green-Beckham needs to do to improve. "That's in the classroom. I think it's just putting the work in without being directed by anybody. Doing it yourself.

"I would do it more (than he's doing)," Mularkey said. "I mean he does do it. I would do it more. He does do it. I'd do it more."

Green-Beckham said he feels like a different player this year compared to his rookie season. He came in at 228 pounds – the lightest he's been since his sophomore year in college – and he's also healthy. A year ago, he battled hamstring issues.

Green-Beckham has also improved mentally, he said.

"Just letting the play go and moving on to the next play,'' he said.

A week into camp, Green-Beckham said he's making progress, and committing himself. But it's clear coaches would like to see more.

"I actually feel like every day I am getting better,'' Green-Beckham said. "Coming in and running, and getting that extra time in the film room with the coaches. I am trying to do those little things to help me get better and better every day. For me, I just have to focus on staying focused.

"Me handling myself, I know I have to put this time in. I have to make plays, and I have to do what the coaches need me to do. I am very motivated. I just have to have that mindset to compete and have fun, and remember to do the details."
