Five Celtics storylines to watch as training camp begins

The Celtics are the betting favorites to win the championship this season. They are three months removed from a trip to the NBA Finals. Ime Udoka's season-long suspension has put a dark cloud over the C's as they start training camp this week.

It is not possible to walk back on the court after the team is told of the news.

Joe Mazzulla is the new head coach of the Celtics. He's been an assistant coach for three seasons. The C's view him as advanced even for his relative experience. The rest of his assistants remain on staff. Celtics coach Brad Stevens is confident in the team and the coaching staff that's gonna take the court on Tuesday.

Rob Williams is out for 8-12 weeks after having another left knee surgery last week. He was instrumental in last year's postseason run.
