After being dominated by Philadelphia 76ers center Joel Embiid on Thursday and ranking in the middle of the NBA in rebounds per game, the Boston Celtics could use some extra depth in the frontcourt. And Jeff Zillgitt of USA Today reports that they are open to conversations to add it.

Currently on the roster, the Celtics have been starting 6-foot-8, 210-pound Jayson Tatum at power forward. And while Tatum is likely a better natural fit at small forward, he'll likely have to play the four in today's smallball-centric NBA, especially on a team like the Celtics.

Third-year center Daniel Theis has played fairly well for the Celtics, but at 6-foot-8 and 245 pounds, the German big man lacks the size you'd like to see in a center.

Off the bench, 6-foot-10 Enes Kanter is a great post scorer and rebounder but is a liability on defense, hence why he has been coming off the bench. Robert Williams III hasn't developed as quickly as most fans would have liked. However, the ultra-athletic 6-foot-8 power forward just turned 22 and has the most potential of any young big man on the roster. 7-foot-6 Tacko Fall is an intriguing option, but will likely need a year or two to develop in the G-League.

On the trade market, the Celtics could go for another undersized big in Kevin Love who could rebound and stretch the floor. They could also target  Love's teammate in Cleveland, Tristan Thompson. Thompson is also slightly undersized but would provide Boston with elite offensive rebounding and a strong interior presence. Also possibly available is Washington Wizards stretch-four Dāvis Bertāns, who is enjoying a breakout season.
