Tuinei played for two seasons at UCLA where he started at defensive tackle as a sophomore, finishing fifth on the team in tackles. The next year, he decided to drop out of the school before facing the possibility of being expelled after a fight incident.[2]
As a junior, he transferred back home to the University of Hawaiʻi, but was suspended for the year, after being indicted on assault charges that led to spending three months in prison. He was nagged by injuries his senior year and played in only seven games, including 5 starts at defensive tackle.[3]
In 2007, he was inducted into the Hawaii Sports Hall of Fame. In 2015, he was inducted into the Polynesian Hall of Fame.[4]
Considered one of the strongest players on the team, in his first two years he played mostly on special teams and short yardage situations, while being a backup at both defensive end and defensive tackle.
In 1987, he was progressing through his second season as the starting left tackle, when he sustained a left knee injury in the Thanksgiving game against the Minnesota Vikings, losing the last month on the injured reserve list. The next year he reinjured the same knee early in the season, but still saw action in 5 games before being put on injured reserve.
In 1989, he didn't miss a play in a game or a practice. In 1990, during a season that experienced a number of players being juggled around the offensive line, Tuinei remained a solid foundation at left tackle, by starting all 13 games he played, and missing 3 contests with a sprained right knee he suffered against the New York Jets.
In 1991, he suffered a groin injury that forced him to miss 4 games, returning to the starting lineup against the Houston Oilers, to help Emmitt Smith lead the NFL in rushing.
In 1992, he started the first 5 games, but injured his back lifting weights in the week leading up to the Kansas City Chiefs contest. He was forced to sit out the game, but was able to return against the Los Angeles Raiders, contributing to Smith earning his second consecutive NFL rushing championship.
In 1994, he suffered back spasms in the first quarter against the Washington Redskins, that required him to spend 2 nights in the hospital and miss the Arizona Cardinals game. He returned to the starting lineup against the Philadelphia Eagles. He helped the offensive line establish a new franchise record by allowing 20 sacks in a season, while being elected for his first Pro Bowl.
In 1995, he contributed to Smith winning his fourth rushing title, score an NFL record 25 rushing touchdowns and gain a club record 1,773 rushing yards. He received his second selection to the Pro Bowl, as part of a line that broke the team record by allowing just 18 sacks in a season.
The next year suffered a torn medial collateral ligament in his right knee in a preseason game against the New England Patriots, which eventually required offseason surgery. Despite the injury, he contributed to the offensive line leading the league in allowing the fewest sacks with 19. He missed playing time against the Atlanta Falcons after re-aggravating his injury in the first quarter. He only sat out the season finale against the Washington Redskins and returned for the playoffs. Knee problems ended his career after the 1997 season, when Larry Allen took over for him at left tackle.
"We just all loved the guy," said former Cowboys quarterbackRoger Staubach. "He was just a gentle giant. He was just one of those unsung players that goes out and does their job. He was one of those kind of players every team needs. He was a role model for the NFL."[6] He suffered knee injuries most of his career, yet he would play a total of 195 games, more than any other Cowboys offensive player ever. He also helped to protect Hall of Fame quarterback Troy Aikman and pave the way for Hall of Famerunning back Smith to become the National Football League all-time leading rusher.
On April 14, 1998, he was released in a salary-cap move,[7] finishing tied with Ed "Too Tall" Jones and Bill Bates for the most seasons in a Cowboy uniform—with 15. He is considered to be one of the greatest offensive tackles in Cowboys franchise history.
Death
In May 1999, Tuinei was found unconscious in his antique Ford car, and he was pronounced dead upon arrival at a hospital in the Dallas suburb of Plano. He had been planning to return to Punahou School to serve as the offensive line coach. The autopsy revealed that Tuinei died of a combination of heroin and a form of the drug ecstasy. His death was ruled an accidental overdose. Upon the release of the autopsy results, Plano police chief Bruce Glasscock was quoted alleging that it was Tuinei's first experience with heroin.[5]
"What you had was a 39-year-old male, 6'5", in excess of 300 pounds, a healthy individual, took one shot of heroin and basically dropped dead as a result", Glasscock said during his press conference regarding Tuinei.[8]
Tuinei got the heroin from four people who belonged to a drug ring. The four men were charged, tried and convicted for conspiracy to distribute heroin and cocaine. Jesus Carbajal received a life sentence. Julian Solis Perez and Andres Milan were sentenced to eleven-year prison terms, and Favian Ramos received a twelve-year sentence.[9]
