The couple met while attending the University of Texas at Austin, where Sam played football for the Longhorns and Blair represented the university’s women’s volleyball program.
After several years together, Sam and Blair married in March 2023. Their wedding took place at Mae’s Ridge, a wedding venue near Austin, Texas.
The Washington Commanders publicly congratulated the couple on March 27, 2023, and the team’s official media guide subsequently confirmed their marriage.
Since their wedding, Blair has supported her husband’s professional football career while continuing to pursue her own interests in education, psychology, and helping children.

Standing 6 feet 3 inches tall, Blair played as a middle blocker. During high school, she earned several prestigious honors, including recognition as a Volleyball Magazine Girls’ Fab 50 selection and a 2016 Under Armour All-America Third Team honoree.
Unfortunately, injuries significantly affected her collegiate volleyball career. In May 2019, the University of Texas announced that she would no longer participate in competitive volleyball after struggling with injuries.
Blair subsequently focused on education and professional development. She studied youth and community studies, with an emphasis on supporting individuals with special needs, and pursued further qualifications in applied behavior analysis.
In March 2023, the Washington Commanders published an article highlighting the careers of players’ partners. The publication identified Blair as Sam Cosmi’s fiancée and reported that she worked at Proud Moments ABA, helping children develop behavioral and communication skills.

According to a December 31, 2025 report by Commanders Wire, Blair went into labor on Christmas evening and delivered a healthy baby boy at approximately 1:46 a.m. the following morning.
The couple had originally expected a scheduled induction, but Tate arrived earlier than anticipated.

He also confirmed that Blair was recovering well after the delivery.
As of now, Clara and Tate Nicholas are the two publicly confirmed children of Sam Cosmi and his wife.
Sam Cosmi’s Parents: Meet Cornel and Rodica Cosmi
Sam Cosmi’s parents are Cornel Cosmi and Rodica Cosmi, Romanian immigrants who moved to the United States before their son was born.
Their immigration story has been an important part of Sam’s personal identity. Both parents experienced the difficulties of starting a new life in another country, and their determination strongly influenced their son’s character.
According to The Washington Post, Cornel’s family left communist Romania during the early 1980s. They spent time in refugee camps in Europe before eventually settling in Texas.
The family initially arrived with very few possessions and had to work hard to establish financial stability.
Sam Cosmi’s Father: Cornel Cosmi
Cornel Cosmi is Sam Cosmi’s father and an automobile mechanic who immigrated to the United States from Romania.
His family fled Romania during the communist era, seeking freedom and greater economic opportunities.
In a July 2021 interview with The Washington Post, Cornel described how his family experienced difficult conditions before reaching the United States.
They spent several months in refugee camps in Italy and Yugoslavia while completing the immigration process.
After settling in Texas, the family began rebuilding its life. Cornel eventually became an automobile mechanic, developing the technical knowledge and work ethic that would later influence his son.
Sam has frequently credited his father with teaching him the importance of discipline, hard work, and attention to detail.
Growing up, he observed Cornel’s dedication to providing for his family and developed a similar approach to his own responsibilities.
During his early NFL career, Sam explained that his father’s willingness to sacrifice for the family motivated him to become a successful professional athlete.
He has also identified his father as one of his childhood heroes, reflecting their close relationship.
Sam Cosmi’s Mother: Rodica Cosmi
Rodica Cosmi is Sam Cosmi’s mother and another important influence on his upbringing.
Like her husband, Rodica comes from Romania and participated in the family’s transition to life in the United States.
Although she has maintained a relatively private personal life, Sam has publicly acknowledged the values she taught him.
He has credited his mother with helping him develop mental toughness, humility, and perseverance.
Rodica emphasized that success requires dedication and that personal achievements should never become an excuse for arrogance.
These lessons became particularly important as Sam progressed from high school football to the University of Texas and eventually the NFL.
In September 2024, while discussing his contract extension with the Washington Commanders, Cosmi thanked his parents and reflected on the sacrifices they made after arriving in America.
For him, the financial security associated with his professional football career represented an opportunity to honor the people who worked hard to provide him with a better childhood.

During his 2024 contract-extension press conference, Cosmi reflected on being a first-generation American and expressed pride in what his parents had accomplished.
