Dameon Pierce took off out of the backfield, swiveling into his route to catch a pass in stride from quarterback C.J. Stroud, and the fluidity and acceleration were obvious to see.

On running plays, with starter Joe Mixon sidelined with a soft-tissue injury, the first carries went to Pierce. And Pierce made the correct read, showing more patience to allow the hole to open on one of offensive coordinator Bobby Slowik’s patented zone schemes. That was a stark contrast to a year ago when Pierce endured a frustrating season without complaint, exercising silence and restraint during a year where his status on the depth chart, workload and productivity all declined.

Pierce was in too much of a rush at times as he tried to learn an unfamiliar strategic approach to running the football. And his body weight and nutrition weren’t where he wanted them to be. So, Pierce switched things up this offseason. He’s down to 210 to 214 from 217 to 218 pounds last year through a diet emphasizing lean meats and vegetables designed by the Texans’ nutritionists.

Pierce feels like a new man, and it shows through his play on the field and the smile on his face.

“I’m feeling comfortable, I’m feeling in shape,” Pierce said. “Last year was like another rookie year for me in terms of unlearning and relearning things. My head was in a thousand places at one time, and that’s not efficient. You can’t play fast. You can’t play clean if you’re thinking a lot, if you’re wondering, ‘What I got on these plays? Who do I have on that? Was I right on this play? So, a lot of the cobwebs and all that are gone. I’m more precise and more sharp, cleaner. Everything just feels right. It’s fun again, bro.

“I ain’t gonna say last year took the fun away from the game, but, man, nobody wants to be hurt. Nobody wants to be on the sidelines. Nobody wants to not be in the action. Nobody wants to not be on the field. So, it was definitely a learning curve. You heard it. Compared to last year to this year, it feels amazing to be back out here and be in the mix and doing my thing the right way. Everything just feels right and comfortable. It’s like football. To not have missed assignments, this is the kind of football I like playing.”

One year after being named a Pro Bowl alternate as one of the top rookie running backs, Pierce was relegated to a complementary role behind Devin “Motor” Singletary -- cheered on his teammate while his numbers took a hit.

Pierce rushed for 416 yards and two touchdowns last season with a 2.9 average per run in 14 games and seven starts, dealing with an ankle injury and a tough adjustment to Slowik’s running system. Pierce gained 939 yards and scored four touchdowns as a Pro Bowl alternate during a dynamic rookie season two years ago, averaging 4.3 yards per run as he established himself as a bruising presence and was awarded the NFL’s Angry Run of the Year for his tackle-busting display against the Jacksonville Jaguars.

Flash forward to training camp this year and Pierce looks primed to bounce back. He’s worked tirelessly this offseason and has added lean muscle, striking a balance between bulk and speed. He’s also operating with much more certainty and less wasted motion in his moves.

While the Texans did acquire Mixon from the Cincinnati Bengals via a trade and signed him to a three-year, $27 million contract extension and drafted Louisville running back Jawhar Jordan, they still have plans for Pierce. Pierce, who has worked diligently this offseason while also taking the time to complete his degree requirements at the University of Florida, figures into the equation as a change of pace behind Mixon and on kickoff returns after his 98-yard kickoff return for a touchdown last season against the Cleveland Browns.

“He came in ready to compete and ready to work,” Slowik said. “And, I mean, last year, there’s always a lot going on. This year, he’s been able to really focus mentally. He’s been able to focus physically to where he’s can hone in on the offense, but he can also hone in on himself.

“And he’s always been a tireless worker. But now he’s seeing the dividends of that and it’s been fun to watch him in OTAs and camp. I mean, he’s doing really good stuff in camp. I mean, it’s been fun to watch, excited to continue to see him grow.”

Pierce wanted to make some changes after last season.

He changed his diet, incorporating more lean proteins and vegetables into his diet. After playing at around 223 to 225 pounds as a rookie fourth-round draft pick from Florida, Pierce has more energy now at a lighter weight and still appears powerful.

“This year, I’ve got way more muscle mass, more lean muscle mass and I feel great,” Pierce said. “I got tips on proper nutrition and it feels good. I really don’t eat red meat no more, but when I do I go crazy. If I’m going to get the red meat, I’m going to get the ox tails and go crazy.”

Yes, Pierce will occasionally treat himself to a steak on a special occasion. Ideally, a six-ounce filet mignon accompanied by asparagus with Hollandaise sauce.

It has to be done just right, not too rare.
