Jim Kelly says he's working with his nephew, Chad Kelly, nonstop to get him back on an NFL team ... and tells TMZ Sports he's confident the young QB will get another shot in the league.

Jim -- his real-life uncle -- has thrown his support behind Chad and is personally helping him get his life back on track .
