Robert Williams developing into one of the best defensive centers in the NBA has been a key reason for the Boston Celtics turning their season around. His versatility and impact near the basket have helped propel the Celtics to one of the best records in the league in the second half of the season.

Unfortunately for Boston, Williams suffered a meniscus tear ad will be sidelined for about a month. His absence comes at a brutal time as the Celtics are in the thick of a huge race for the top seed in the Eastern Conference. Especially because they lack serious depth, they will greatly miss Williams during his recovery time.

Williams declared he would bounce back from the injury. He also sent a heartfelt message to Celtics fans, letting them know that his surgery was successful and that he appreciates them for showing him love.

Williams is averaging 10.0 points, 9.6 rebounds, 2.2 blocks and 2.0 assists per game this season. His efficient scoring as a lob threat (73.6 percent from the field) gives the Celtics an easy scoring route on offense while his defense helps lead the best unit in the league. They will have to lean on Al Horford and Daniel Theis for impact in the frontcourt while Williams recovers.

Boston is racing towards the top with the Miami Heat, Philadelphia 76ers and Milwaukee Bucks. Even if they don't make it to the top, they can still make a deep playoff run. But without Williams, their chances of finally breaking through to the Finals are very slim.
