Could 6-foot-10 center Robert Williams develop into a crucial rotation piece for the Boston Celtics in the upcoming season? According to head coach Brad Stevens, if Williams' offseason is any indication, he is in a good place.

The 21-year-old Williams is entering his second professional season in the NBA after he was selected by the Celtics with the 27th overall pick in the 2018 draft. Williams, sometimes known by his bubbling nickname “Time Lord,” only appeared in 32 games during his rookie season, however. He saw his time divided between Boston and their G League affiliate Maine Red Claws.

Nonetheless, Stevens said Williams put in “as good a summer as anybody.”

Stevens also noted Williams' improved communication, which came as a surprise, per A. Sherrod Blakely of NBC Sports Boston.

The former Aggie tallied 81 points in 283 minutes in his first season while grabbing 81 total rebounds and swatting 40 shots.

The NBA's offseason and free agency period brought many changes for Stevens, Boston and the frontcourt. All-Star big man Al Horford left the franchise for the Atlantic Division rival Philadelphia 76ers and the C's sent center Aron Baynes to the Phoenix Suns in a trade in July for a 2020 first-round draft pick.

Meanwhile, Boston signed former New York Knicks big man Enes Kanter, presumably to start at center, and selected Tennessee standout power forward Grant Williams with the 22nd overall pick in the 2019 draft.

Nevertheless, Robert Williams will surely be needed by Stevens and the coaching staff to move the franchise forward as they prepare for what is expected to be tough battle for the Eastern Conference crown.
