Marshall has openly discussed his struggles with mental illness as a youth and young sports star, with a history of off-field problems and being termed "reckless" in his early career.
Since being traded to the Bears, Marshall seems to have righted himself and is acknowledging with his pledge that there is much work to be done with mental illness in young people, especially those who come from stressful environments of poverty and parental substance abuse.
On May 20, Marshall appeared on ESPN's "First Take" to discuss his support for the mental health community. The ESPN interview can be seen on YouTube.
