Atlanta Hawks’ Mike Scott -- Videotaped Confession ... Drugs Were Mine, Not My Brother's (VIDEO)

Atlanta Hawks forward Mike Scott took a felony bullet during a recorded interrogation -- admitting all the drugs cops found in his car were his ... so his kid brother wouldn't get in trouble.

TMZ Sports obtained the video of Banks County Sheriff's deputies questioning Scott about the July 30 traffic stop. As we reported, Scott's 20-year-old bro, Antonn, was driving when deputies pulled him over for speeding. They eventually found more than an ounce of weed and 10 grams of Molly in the vehicle.

In the video, a slumped over Scott explains why Antonn didn't immediately pull over -- cops chased him for 2 miles -- and he's oddly calm as he takes full responsibility for the stash of drugs. Scott 's biggest concern was whether his arrest would be "a public thing." The deputy gave him a reality check ... gently.
