Retired NFL linebacker Tim Johnson knows how to deliver a hit—and he knows what it takes to stop the impact of one. 

Johnson, a professional football player for more than 20 years, launched his career as NCAA Division 1-AA Defensive Player of the Year in 2000. He went on to play for the Baltimore Ravens, Chicago Bears and the Oakland Raiders, where he blocked a punt that advanced the Raiders in Super Bowl XXXVII. Now retired, he’s an entrepreneur who’s supporting the National Football League – and the nation – with a new type of defense. 

Traumatic brain injuries (TBIs) have become a top concern for the NFL. In 2022, the NFL saw 18% more concussions than the year before, and 10% of TBIs in the U.S. are from sports and recreational activities. When the NFL kicked off the Helmet Challenge to enhance player safety, Johnson decided he had a new mission to tackle. He started the Head Impact Prevention youth football league in 2017 to create an inclusive, safer game for kids, but he was ready to find better ways to protect players. Professional athletes are not the only ones at higher risk for head injuries and their long-term effects. Between 2000 and 2019, almost 414,000 veterans sustained severe head trauma, making TBIs one of the most common wounds from the Iraq and Afghanistan wars. Even mild concussions can increase the chances of Alzheimer’s Disease, Parkinson’s Disease, dementia and seizures—and Johnson is determined to find a solution. 

With his business H.I.P. MD, Johnson is developing a first-of-its-kind helmet for military personnel, first responders and athletes. He’s always had a natural instinct to defend, but watching fighter jets fly over NFL stadiums and being part of the league’s patriotism inspired Johnson to protect Team USA.

“We’re fortunate to play the game, but our war fighters put their lives on the line for their families and their country,” he said. “I learned a lot from the league, and I want to build a business to help our defense, our infrastructure and our communities. That’s the team I want to be on.”

Gearing up for his next big play in manufacturing, Johnson headed to METAL’s Ohio State University bootcamp to see how metal can be used to protect service members from blast impacts and ballistic materials like shrapnel.   

“We want to put the war fighters first,” Johnson said. “The military is the most important entity in the world.”

Engineering a Winning Solution

Johnson’s H.I.P. helmet, the Brain Crown, is inspired by nature to be both strong and resilient. Its design, based on biomimicking, replicates animal traits that are essential to survival after a head-to-head collision or an enemy attack. By mimicking the horns on a ram, an armadillo’s armor and the protection of a woodpecker’s beak, the helmet distributes force from an impact around its structure, away from the skull and brain.

With a prototype in development, Johnson wondered if metal could be a critical missing piece. As a self-described “steel guy,” growing up in manufacturing towns like Fairfield, Alabama and  Youngstown, Ohio, he was ready to melt some metal and find out for himself.

For four days, Johnson got a hands-on look at the possibilities of metal manufacturing. He cast a mini anvil engraved with “H.I.P. MD,” an aluminum mug, a bronze coin, and finally a creation of his own—a football on a pedestal that ironically resembles a helmet. The best part for Johnson was practicing every part of a pour: guiding the ladle, filling it with liquid metal, and carefully turning it over onto a mold to create something new. 

“The hands-on participation was amazing,” Johnson said, adding that he also gained experience using CAD software to develop 3D mold designs. “It was a really thorough four days. If you’re looking for a metalcasting opportunity, this is the place to go.”

What stood out the most to METAL instructor Jason Walker was Johnson’s enthusiasm. Walker’s number one goal for METAL’s bootcamps is to introduce participants to manufacturing skills and experiences they won’t get in a classroom.

“Most engineering students graduate from universities having never seen a metalcasting or a rolling mill and they’ve never been in a machine shop,” said Walker, who serves as the Director of Materials and Process at The Ohio State University’s Center for Design and Manufacturing Excellence. “I believe it makes them much better at their job, whether it’s engineering or not, to understand the process better.”

But the bootcamp isn’t just for students—it’s for anyone who wants to learn more about metalcasting. Walker invites everyone from high school students to manufacturing professionals and business owners like Johnson, even if they’ve never stepped foot inside a foundry before. 

“All of this is helping to build a workforce and a country that is resilient and able to manufacture the products we need,” Walker said, which Johnson agrees will be critical to the future of H.I.P. helmets. 

Training MVPs in Manufacturing

Johnson’s helmet prototype has been in development for five years. As he thinks about how to build, test and deliver a product that can protect the nation’s Armed Forces, he’ll need foundry-ready engineers. 

“We need to figure out how to make something that’s tested and proven, and then we can go to market. We’re going to need people,” Johnson emphasized. “I’m really interested in learning about manufacturing, whether it’s additive or subtractive, and learning how to create jobs and opportunities for people.” 

Eventually, Johnson would like H.I.P. MD to expand beyond helmets to shoulder pads and other body armor options for all professions and ages, from aerospace to youth sports. But first, Johnson needs to understand the processes, materials and teamwork that will make the Brain Crown a reality—and METAL’s bootcamp helped him do just that. 

“The passion and the mission behind the business is driving it. It’s not a sale or a product—it’s saving the minds of our youth and protecting the future of sports and our war fighters,” Johnson said. “We want to make an impact in the world.”
