The Rams legend did an interview with OSDB on Wednesday ... and told them he truly believes change in leadership could lead to more Black coaches in the league.

"We’re being told basically that we’re good enough to play the game, but that we don’t have the brainpower to coach the game," Dickerson said. "The only way this is going to change is at the top of the power structure."

In his lawsuit ... Flores alleged teams were racist in their hiring practices -- claiming owners were only interviewing him and other Black candidates to satisfy league rules before going on to hire white coaches.

Dickerson made it clear he believes the lack of Black head coaches in the league is a problem ... and he said in addition to changing out commissioners, adding Black owners could help things.

"A shift in power is the only thing that will change the way it is," E.D. said. "You’re not going to make everyone happy, and I understand that. That’s not how life works, but we need to make real progress."

The former running back pointed toward the NBA as an org. the NFL should model itself after -- saying he believes its structure at the top has led to more diversity in its coaching ranks.
