NBA Rumors: Celtics could draft Oregon's Bol Bol at No. 20 or 22 originally appeared on nbcsportsboston.com

The Boston Celtics could move any one of their three first-round picks in the 2019 NBA Draft.

But if they keep the 20th and/or 22nd selections, they could take a flier on a big man with tantalizing upside.

Several teams believe Oregon center Bol Bol won't fall past the Celtics in the late first round, Bleacher Report's Jonathan Wasserman reported Thursday.

Some believed the 7-foot-2 Sudanese center -- the son of former NBA center Manute Bol -- could be a lottery pick out of high school, and he averaged 21 points, 9.6 rebounds and 2.7 blocks per game during his first nine contests at Oregon. A left foot injury ended his freshman season prematurely, though, and concerns about his health and unpolished game have lowered his draft stock.

The Celtics could have an acute need for a big man if they let Al Horford walk in free agency and trade Aron Baynes , and it appears they'd be willing to roll the dice on the 19-year-old Bol if he's still around at 20 or 22.

That's a big "if," as the Indiana Pacers seemingly have interest in Bol at No. 18, according to John Canzano of the Oregonian.
