More on Smith

ESPN’s Nick Wagoner wrote this regarding Aldon Smith:

“Once viewed as one of the league’s top young players, Smith’s star-crossed career ended in 2020 after one season with the Cowboys.

As a rookie, Smith burst on the scene with 14 sacks and 27 quarterback hits on his way to finishing second in Defensive Rookie of the Year balloting. He followed with his best NFL season in 2012, posting 19.5 sacks and 29 quarterback hits as he earned Pro Bowl and All Pro honors. Those 19.5 sacks still stand as a franchise record for a season. …Smith signed with the Raiders in September 2015, but the league suspended him for a year in November 2015 for again violating the league’s substance abuse policy.”

After retiring from the NFL, Smith turned his personal challenges into an opportunity to help the next generation of athletes navigate the demands that come with life in professional sports. He launched a program called “I.M. Loading,” which stands for “Intelligent Movement,” with a focus on mentorship, personal development, and recovery support for individuals facing similar obstacles.

That same offseason, Smith worked directly with the rookie classes of the Jacksonville Jaguars and Raiders, sharing lessons from his own experiences and helping young players prepare for the realities of the NFL.

During an appearance on Keyshawn Johnson’s “All Facts, No Breaks” podcast in June 2024, Smith reflected on his journey and explained why he wanted to use his story as a learning experience for others entering the league.

“I’m grateful for my journey so far because of where I am now,” Smith said. “Just my plan, how I want to interact with the world I’m in and the people I get to meet, I don’t think it would have been possible if I didn’t have the journey I’ve had so far.”
