The Boston Celtics are on a mission this upcoming season to make the NBA Finals after coming so close last season despite a slew of key injuries. Now, with everyone back healthy and ready to go, the Celtics' mission is simple: Make the NBA Finals and compete for a championship.

As they welcome their main stars back, they also bring in rookie center Robert Williams. Williams showed promise for Texas A&M, and the Celtics selected the big man with the 27th pick in the 2018 NBA Draft.

Williams was thrown into the deep end right away, getting an up close look at the work ethic required to be successful within the franchise by other big men Al Horford and Aron Baynes.

Williams was once projected to be a lottery pick, but he slipped down the draft board as there was questions and concerns about his work ethic. He has undergone criticism for missing practices and showing up late for team functions, but he will look to put that all behind him and impress his new teammates and coaching staff as training camp approaches.

Despite his reputation, Williams is now lucky enough to find himself with a franchise that is at the pinnacle of professionalism and hard work. In his new green threads he will be forced to put in work, and continue to follow the example set for him by the older veterans.

Williams averaged 10.4 points. 9.2 rebounds and 2.7 blocks per game last season in college, and is very much a part of the Celtics' plans moving forward. Most importantly, he now knows what it takes to succeed in the business.
