Career and legacy
Aldon Smith died at 36, according to the San Francisco 49ers. The team said he would be remembered not only for his play, but also for the smile that stood out to teammates and others around him.
Smith was drafted seventh overall out of Missouri in 2011 and quickly became one of the NFL’s most disruptive pass rushers. In his rookie season, he posted 14 sacks, which the article notes was the second-most by a rookie in league history. The next year was even better: he reached 19.5 sacks, earned First Team All-Pro honors, and set a franchise record for the 49ers.
He also started for San Francisco in Super Bowl XLVII against the Baltimore Ravens, showing how central he had become to the team’s defense. The article describes his early impact as one of the best rookie seasons the league had seen.
A career derailed
Smith’s football story was also shaped by repeated suspensions. The article says he was punished multiple times for violations of the NFL’s substance abuse and personal conduct policies. After the 2014-2015 season, the 49ers released him, and he later spent time with the Oakland Raiders.
He appeared for the Raiders in 2015, then missed four straight seasons because of suspension before returning in 2020 with the Dallas Cowboys. That ended up being his final NFL season.
