Jadeveon Clowney -- Entourage Concerns Are BS ... Says Step-Dad

Jadeveon Clowney is no dumb ass... and would never jeopardize his NFL Draft status by hanging out with bad people ... so says JC's step-dad, the man who raised him.

After reports surfaced that NFL teams were concerned about Jadeveon's "entourage" ... the South Carolina superstar's step-dad told TMZ Sports Clowney runs with a good crowd.

"Jadeveon makes good decisions ... including the people who he hangs out with."

Clowney's step-dad adds, "His friends are his friends, but overall he is smart enough to make the right decisions."

"He's a good kid."
