Josh McDaniels out ... Andre Rison in?!?
The ex-NFL star says if he had things his way, that'd absolutely be the case in Las Vegas ... telling TMZ Sports he "would love to" be the next head coach of the Raiders.
"[Mark Davis] knows that," the former Raiders wideout said. "And, I think the whole world knows it as well."
It might sound farfetched to some ... but Rison has quietly been working to be the honcho of a major football team for years.
The 55-year-old tells us over a decade ago he began the process of learning the coaching ropes alongside Deion Sanders .
