Alabama All-American forward Brandon Miller will enter the NBA draft.

The decision, which was reported on Thursday, comes as no surprise for the 20-year-old Miller, who excelled on the basketball court but was also associated with a major off-the-court situation as he was involved in a fatal shooting in January.

A projected top-5 pick in the draft, the 6-foot-9 Miller averaged 18.8 points and 8.2 rebounds while connecting on 38 per cent of his shots from 3-point range in leading Alabama to the SEC regular-season and conference title.

He helped the Crimson Tide to their first No.1 ranking in The AP poll in 20 years and first No.1 seed in the NCAA Tournament.

A groin injury late in the season slowed his production in the NCAA Tournament, and Alabama were ousted by San Diego State in the Sweet 16.

Miller played in all 37 games for Alabama this past season despite his involvement with a fatal shooting on January 15.

According to police testimony, Miller brought the gun belonging to former Alabama player Darius Miles to Miles, and Miles and another man were charged with capital murder in the fatal shooting of 23-year-old Jamea Harris.

Miller’s attorney said Miller never handled the gun and did not know Miles' intension.

Miller was never charged with a crime and was not punished by the team.

The decision by Crimson Tide coach Nate Oates to allow Miller to continue to play as the school was in the midst of an historic season was criticised by countless pundits.
