Ben Simmons has publicly declared for the 2016 NBA Draft.

"I'm making it official," Simmons said late Sunday night.

Simmons is widely expected to be the first or second player selected in the draft.

Adrian Wojnarowski previously reported Simmons will sign with Rich Paul of Klutch Sports.

In his lone season at LSU, Simmons averaged 19.2 points on 56 percent shooting to go with 11.8 rebounds, 4.8 assists and 2.0 steals per game.
