01 / Biography
Life and background
Suspension and blackballing
Kosar’s unblocked blindside blitz injured Zach on January 11, 2019, during the 2018 season’s playoffs against Philadelphia. The Eagles won 26–18; the hit came with 6:33 left in the fourth quarter on third-and-six, with Philadelphia leading 26–10. Public outrage followed the injury. The league justified his 2019 suspension by the severity of the injury, and he accepted his fate.
After the suspension, Kosar was eligible to sign with any team. The anticipated public outrage made signing him seem not worth the cost. He was blackballed rather than permanently barred by a formal eligibility rule. The league never acknowledged wrongdoing.
Zach forgave him almost immediately and personally visited him to say that he held no grudge. He then publicly urged teams to give Kosar another chance. They became close friends and remained in contact. Kosar avoided publicly discussing how fellow players had treated him.
Childhood and personality
DeShaun grew up in a supportive home with interests beyond sports. He was private and reserved, but also quiet, thoughtful and warm.
Life after the backlash
Following Zach’s injury and the public backlash, DeShaun withdrew from public life. He later stayed involved through private mentoring of young players, charity work and community involvement.
Private life
DeShaun was single and had no children.

The earlier warnings and unequal response
Cameron Knox had deliberately delivered a dirty blindside hit on Los Angeles Rams receiver Jaxson Foster in Week 13 of 2017. Foster suffered a concussion, missed four games and returned; Knox received no fine, suspension or other NFL punishment. Earlier that season, Myles Garrett’s hit had torn Jason Harris’s ACL, but Garrett was not widely considered dirty or malicious.
The commissioner had not meaningfully reformed the league after either controversy. After McCauley’s coma, the earlier incidents resurfaced in criticism of the NFL’s repeated inaction. Kosar was suspended in 2019 and then effectively blackballed despite remaining eligible to play. The disparity exposed the league’s inconsistent response.
02 / Career & Football Identity
The player and the résumé
Kosar was not a dirty player: no priors, no headhunting reputation and no pattern of borderline hits. The play that placed Zach McCauley in a coma was an ordinary football play that ended catastrophically.
He was suspended for 2019, before the formal McCauley Rules existed, and then effectively blackballed by teams unwilling to face the outrage over signing him. That treatment made him an institutional scapegoat rather than a player receiving ordinary league discipline.
After McCauley reached out and forgave him, Kosar joined Team For. He could have spent his life demanding vindication; instead, he decided his career was already gone and chose future safety over his own grievance.

What the life and résumé mean
Kosar is the paradox at the center of the debate: the person most unfairly harmed by the public reaction still believed something useful should come from it.
Supporting protection did not turn the hit into intentional violence or excuse the league’s treatment of him.
