Watch: Robert Williams watches as he's drafted by the Celtics

The Boston Celtics newly drafted big man, Robert Williams, wasn't in the Barclays Center on the night he entered into the NBA. However, surrounded by his family and friends in his hometown of Shreveport, Williams was still extremely pleased to find out he'd be a Celtic.

The former Texas A&M center slipped down the draft boards from his expected position in the late-lottery to middle first-round. Head coach Brad Stevens was elated to be able to nab Williams so deep in the draft.

"Danny (Ainge) and Mike (Zarren) really started talking about him around 17 or 18," Stevens said according to Jared Weiss. "He's a really talented guy. There's a lot of good players out there and each pick, we were more and more that he would be available at 27."

Williams seems pretty ecstatic as well. He joins a contender and now will have the opportunity to learn from all-stars such as Al Horford, Kyrie Irving, and Gordon Hayward. Boston might've just landed the steal of the draft if the 6-foot-9, 240-pound prospect begins to develop into their center of the future.
