Darren Waller used to hate football. With a passion.

That fact contrasts with the joy exuded while playing now as an elite NFL tight end. He loved every minute of a breakout Raiders season where he had 90 catches for 1,145 yards, but he's most proud of being consistent and, for the first time in forever, being someone you can count on.

Waller has been clean and sober more than two years now. That change has brought happiness back to his life and the game he once despised.

“I hated football from high school up until I got suspended [in 2017],” Waller said. “The sport was just a means to impress people and seem cool and cover up all these voids. I thought that, if I was successful, I could be happy. It wasn’t doing the trick, so there was a huge void in me I thought I could fill with drugs and alcohol.

“It took me having a near-death experience to question the things I was doing in my life. I stepped away from the game for a bit. If it was God’s plan for me to come back to the game, it’s now clear that it was. I came back with a new perspective and started enjoying it. I was open to coaches and have relationships with these people.”

The near-death experience came from a bad batch of pills two months after his yearlong suspension for violating the NFL’s substance abuse policy while with the Baltimore Ravens, when he sat in his car fighting to stay awake while thinking he might not make it out alive. Waller went to rehab shortly after that, a life choice he considers the foundation of all the good that has come since.

Waller’s personal life improved quickly, but his career didn’t really take off until the Raiders signed him off the Ravens practice squad late in 2018 and he started working with tight ends coach Frank Smith.

Smith challenged Waller to be great, a goal achieved in a shockingly short span. Waller’s now considered among the NFL’s elite tight ends and has become a role model for so many struggling with addiction by telling his story to anyone who will listen.

Waller believes that Smith unlocked true potential by caring about the person over the player, helping him in recovery and on the football field. That’s why Waller honored Smith at this year’s Coaching Corps’ Game Changer Awards, where athletes from different Bay Area professional sports teams honor coaches special in their lives.

Waller honored Smith at a Thursday ceremony in San Francisco, which will be broadcast Tuesday at 7:30 p.m. PT on NBC Sports Bay Area.

“I never had a relationship with a coach like I do with Frank,” Waller said. “I honestly text him more than I text my friends. We laugh every day at practice, but I seriously respect him as a teacher and a coach and an authority figure you can talk to as a friend. Nothing’s off limits. We can be real and honest with each other about everything. That’s so important to me, having him in my life.”

Smith values his relationship with Waller, which has grown over their two years working together.

“He’s an extremely intelligent person who is athletic,” Smith said. “But, if you don’t love football and give it everything you’ve got, you won’t progress. He’d be the first to tell you he wouldn’t sacrifice for the game. We weren’t seeing the best version of him. We were seeing a clouded version of himself blurred by his substance abuse. Then football was taken away, and he learned what he wanted to do.

"Now we’re seeing the full commitment, the full potential be realized.”

Smith admits that coaching Waller is different. His commitment to recovery mandates more involvement in Waller’s personal life, making sure his support system is in place. Smith took on that responsibility without hesitation, balancing his personal and professional duties while remaining an authority figure. He recognized Waller as a special case right away, that he was working with someone who could be great.

“He was humble. He was hungry to learn and hungry to work,” Smith said. “With his story, you can see every day how he cherishes life and embraces every obstacle. He never makes an excuse for anything, even with things that somebody else does. He’s the type of person who really has an effect on you, especially if you let him show you his transformative process.”

Waller let Smith in right away. He’s an open book about his struggles with drugs and alcohol and could tell that his position coach would help him in all aspects and stoke his passion for the game he thought he’d lost forever.

“Frank helped so much with my transition to the Raiders,” Waller said. “He has a friend that was in recovery like I am, who worked the 12-step program and went to rehab. He was able to understand me by understanding his friend. We learned a lot from each other, and he was able to welcome me in without putting too much pressure on me. But he wasn’t allowing me to be someone just happy to be there. He had me set goals, something I never did before that.

"He really opened my eyes to the fact that I could be great. I never really thought I could be great. I was too worried about all the pressure and the negative things. I never saw the game in a positive light. He helped me see that football can be so much fun if you’re not worried about things outside of what you can control.”
