Late Sam Mills, Carolina and New Orleans football player, to be inducted into the Pro Football Hall of Fame

Perhaps the late Sam Mills would have been a blue-chip college recruit and high NFL draft pick had someone invented — as the 5-foot-9 linebacker memorably suggested — “a computer to measure heart.”

Mills played Division III college football and was not drafted. That made his rise to stardom with the New Orleans Saints and Carolina Panthers — and his enshrinement in the Pro Football Hall of Fame in Canton, Ohio, this weekend — all the more remarkable.

The player nicknamed Field Mouse had the will to “keep pounding,” as he’d famously say. It made him an inspiration to people facing long odds in many aspects of life, whether they were undersized football prospects or cancer patients.

“I get emotional talking about him and I always have, because the darn guy was special,” said Jim Mora, who coached Mills in the USFL with the Philadelphia and Baltimore Stars, and then with the Saints. “I loved the guy.”

Former Saints quarterback Bobby Hebert was struck by how little Mills resembled an NFL player in public. Not only was Mills a bit shorter than the average guy on the street, but he wore prescription glasses and had an air of politeness and approachability.

“He was a straight-and-narrow, great guy, just down to earth,” Hebert said, noting that Mills also ran Bible study with the Saints. “Not only was he a leader, like X’s and O’s, but also a spiritual leader. … Sam was as tough as they come on the field and a perfect gentleman off.”

Hebert also marveled at Mills’ ability to so thoroughly win over the fan bases of two long-time divisional rivals.

“You know, I go to the same division, from the Saints to the Falcons, and I’m a mercenary,” Hebert said. “Sam’s a hero for both” New Orleans and Carolina.

Mills was part of New Orleans’ vaunted “Dome Patrol,” which included fellow Hall of Famer Rickey Jackson, as well as Vaughn Johnson and Pat Swilling, and is widely cited as one of the best four-linebacker units in NFL history.

Saints players who’d gaze downward at Mills in defensive huddles “all looked up to him,” Mora said. “Maybe they felt like he was an overachiever. He wasn’t. He was just that good.”

Outside the Panthers’ home stadium stands a statue of Mills wearing his No. 51 jersey. Mills spent the last three of his 12 NFL seasons in Carolina. In 1996, his second with the Panthers, he was named All-Pro. He also went into coaching with Carolina and was an assistant when he was diagnosed with intestinal cancer before the 2003 season.

Mills kept coaching during his treatment and made what is known as his “keep pounding” speech on the eve of the club’s Super Bowl matchup with New England at the end of that season.

“When I found out I had cancer, there were two things I could do: quit or keep pounding,” Mills said then. “I’m a fighter. I kept pounding. You’re fighters, too. Keep pounding!”

The quarterback of that Panthers team was Louisiana native Jake Delhomme, who grew up watching Mills call the Saints’ pre-snap defensive signals, fearlessly shed blocks from offensive linemen who dwarfed him and then plant ball carriers on their backs.

“I always kind of revered Sam Mills,” Delhomme said. “I was that young kid that was like: ‘Man, that’s the undersized guy. That’s the guy that made it. That’s the Field Mouse.’”

During the speech, “You felt that emotion,” Delhomme recalled. “It was like, ‘Oh my God, let’s put on the uniform now. Let’s play right now!’”

But Delhomme’s most poignant memory of Mills came earlier that season, a few days after a loss to Dallas. Delhomme recalled feeling sore, sluggish and uncharacteristically sorry for himself as he walked to practice. Then Mills jogged past, slapped Delhomme on the back side and said, “Let’s go get better.”

Delhomme refers to that moment as an awakening in which he told himself: “You need to grow up and try to be just a tenth of this guy.”

“Everybody knew he was dying,” Delhomme continued. “He was doing chemo. And he’s running out to practice … and he’s going to coach his ass off.”

Mills was just 45 when he died in April 2005. “Keep pounding” remains the Panthers’ tag line.

“He lived ‘keep pounding,’ and it resonates with people because it’s real and because it’s not just a sports thing,” said Mills’ eldest son, Washington Commanders defensive assistant coach Sam Mills III.

“I feel honored that I’ve had a chance to be around someone that’s touched so many people’s lives,” Mills III added. “You see how many people he’s affected with his story of small school or small stature. And then when you go post-cancer, you see how many other people who have nothing to do with football would come up and speak to him about their fight. I feel privileged to have been a part of that — to see what that has meant to people, to see what stopping and talking to someone for two minutes out of your day means to people.”

When Mills was playing high school football in Long Branch, New Jersey, he had little expectation of going to college until his coach persuaded him. He was good enough at Montclair State to receive training camp invitations from the Cleveland Browns and Toronto Argonauts of the CFL. Neither team kept him because of concerns about his size, and he went back to New Jersey to teach photography at East Orange High School and serve as an assistant football coach.

But when the USFL was preparing for its inaugural season in 1983, then-Brown’s coach Sam Rutigliano, never comfortable with Cleveland’s decision to cut Mills, encouraged Philadelphia Stars general manager Carl Peterson to take a serious look at him.

Mora, then the Stars’ head coach, recalled linebacker coach Vince Tobin asserting: “I don’t care how tall he is. This guy is a football player.”

When Mora started to evaluate Mills more closely, he noticed that Mills was quick, had exceptional lower body strength and that his shorter stature could be an asset.

Linebackers are taught to get their shoulder-pad level below that of the player they’re trying to tackle because it gives them leverage. Having also been a high school wrestler, Mills knew all about leverage and taking opponents to the ground.

“In football,” Mora noted, “sometimes the low man wins.”

Mills never loafed during practice and always made meetings on time, Mora said. He wasn’t just a run-stuffer, either. He could cover tight ends and running backs out of the backfield, and his positional soundness and anticipation of QBs’ intentions helped him effectively cover players who were taller than he was.

When Mora was hired by the Saints in 1986, he persuaded the club to sign Mills.

In 181 NFL games, Mills made 1,265 tackles, had 23 fumble recoveries, forced 22 fumbles, had 20 1/2 sacks and intercepted 11 passes. He also was part of the first four playoff teams in New Orleans Saints history and the first in Panthers history.

“It was hard to find negatives about the guy on or off the field,” Mora said. “He probably would have had a great future as a coach. He knew the game, he studied the game and always prepared mentally. Players would have loved playing for him.”

Mora has coached other Hall of Fame players — household names including quarterback Peyton Manning and receiver Marvin Harrison. Seeing Mills enter the Hall will be gratifying for Mora in a different way.

Many football fans “don’t know Sam Mills unless they are astute, older football guys,” Mora said. “He’s one of the best guys I ever coached, but I always have to explain a little bit about who Sam Mills was.”

Maybe less so after Mills’ enshrinement.
