The Boston Celtics' bench will make or break the 2012-13 season. Each role player must excel at his job in order for the team to truly be successful.
Rajon Rondo can score, defend, assist and rebound. However, most players aren't that well-rounded. For example, Avery Bradley is an amazing perimeter defender, but his offense is just good. Jason Terry excels when coming off the bench, but he probably couldn't put up the same numbers if he was a starter.
Each player on the Boston Celtics bench has a specific role. General manager Danny Ainge handpicked them for a reason. Understanding these players and their roles will give fans a better understanding of why the Celtics are better than they were last year.
