Isaiah Kacyvenski

While he was a freshman at Harvard, Kacyvenski came across items that belonged to his mother. Among the items he found a picture of his mother wearing a Harvard sweatshirt and her Bible with a passage highlighted: "Can a woman forget her own baby and not love the child she bore? Even if a mother should forget her child, I will never forget you. I can never forget you! I have written you in the palm of my hands." – Isaiah 49:15. Kacyvenski took these things as signs that he was making the right decision in his life. Coincidentally, 49 was also the jersey number he had been randomly assigned upon arrival at Harvard.

For four years, Kacyvenski started every game at Harvard University. As a freshman, he won the Ivy League Rookie of the Year award, and for three years, won All-Ivy League first team honors. As a senior, he had a school single-season record 135 tackles, and for his college career, finished with a school career-record 395 tackles, 4.5 sacks, 11 interceptions, and 8 fumble recoveries. He received the Nils V. "Swede" Nelson Award given to "best, most academically talented" football player in New England, and also the Harvard University Male Athlete of the Year following his senior season. Isaiah was a finalist for the Buck Buchanan Award that is given to the top 1-AA defensive player in the country, as well as a 1st Team Associated Press All-American.

Kacyvenski was chosen to announce the Seattle Seahawks second round draft pick from the podium during the 2013 NFL Draft, one of 32 NFL Greats chosen.

Kacyvenski earned his MBA from Harvard Business School in 2011.

On October 24, 2010, Kacyvenski was invited back to Seattle to raise the famous 12th Man Flag before the Seahawks played the Cardinals.

However, in September 2008, it was reported that Kacyvenski had decided to retire. A knee injury kept him out of the 2007 season and it was recommended by Dr. James Andrews that he not continue playing.

Also in September, Kacyvenski, the first of five other former NFL players that soon followed, agreed to donate his brain upon his death to the Center for the Study of Traumatic Encephalopathy, a joint program between the Boston University School of Medicine and Sports Legacy Institute in order to have research into the effects of concussions on the human brain performed. Kacyvenski, like many NFL players, suffered a number of concussions over the course of his playing career. At the end of 2008, Isaiah was awarded the PETA Compassionate Action Award after being the first professional athlete to donate his brain to science.

He was elected to the Board of Directors of Sports Legacy Institute in 2008, and has used this as a platform for awareness surrounding head trauma and making contact sports safer to play.

Kacyvenski also spent time with the St. Louis Rams and Oakland Raiders. After spending the 2007 season out of football trying to return from microfracture surgery, Kacyvenski officially announced his retirement in 2008.

An unrestricted free agent in the 2007 offseason, Kacyvenski signed a one-year contract with the Oakland Raiders on July 11. He was placed on season-ending injured reserve on August 7 and released with an injury settlement a week later after undergoing microfracture surgery on his leg.

On the July 12, 2007 episode of The Oprah Winfrey Show, Kacyvenski appeared as the first guest to talk about his rough childhood and reconciliation with his abusive father.

Kacyvenski was featured in an NFL Films production that was nominated for an Emmy Award for Outstanding Long Feature in 2007.

Kacyvenski played six-plus seasons with the Seattle Seahawks recording 267 tackles in 90 games and was elected as the Special Teams Captain 3 years in a row. In 2002, Isaiah earned the starting job at Middle Linebacker, after battling for the position with Orlando Huff. In 2005, Kacyvenski was Special Teams Captain of the Seattle Seahawks and helped lead the team to Super Bowl XL, which was played in Detroit, Michigan. He was released by the team on September 30, 2006.

Kacyvenski signed a one-year contract with the St. Louis Rams on October 3, 2006, and played in ten games for them during the remainder of the 2006 season after suffering 2 concussions 3 weeks apart.

In 2000, Kacyvenski was selected in the 4th round of the NFL draft by the Seattle Seahawks and became the highest draft pick in Harvard history. He graduated cum laude with a pre-med degree, but elected to miss his commencement ceremony to attend the first days of football training camp. His father attended the ceremony in cap and gown in Kacyvenski's stead and received the Harvard diploma for his son.
