WALTHAM, Mass. -- When Jason Terry arrived in Boston this summer, a member of the Celtics' staff pulled aside the former Sixth Man of the Year to note that the Boston bench had scored a mere two points in the season-ending, Game 7 loss to the Miami Heat in the Eastern Conference finals.

Terry promised that wouldn't happen on his watch. And while the bench production hasn't been nearly that anemic over the first three games of the 2012-13 season, Boston's reserves have still been outscored 131-87 by opposing second units.

And, maybe not surprisingly, that doesn't sit particularly well with Terry.

"Oh, that's frustrating," he said. "But again, I take that squarely upon my shoulders, and this is a new week. I'm looking to go this week and hopefully we can get three consecutive games of outscoring [the opponent's] bench, and we'll see what happens. But that's the goal, and we try to take it game-by-game, but hopefully we'll take it week-by-week, and last week was a disappointing one for us, but this is another opportunity and that's the beauty of it."

Much of the optimism surrounding the Celtics entering the new season stemmed from a revamped and reloaded bench that included two former Sixth Men of the Year (Terry and Leandro Barbosa), the return of both Jeff Green and Chris Wilcox from heart surgeries last season, and a restocked frontcourt with veterans Jason Collins and Darko Milicic, and rookies Jared Sullinger and Fab Melo.

But through the first three games of the season, Boston's bench hasn't offered a consistent support system for the Big Three core of Rajon Rondo, Paul Pierce and Kevin Garnett. Much of the bench's output has come in the fourth quarter of losses to Miami and Milwaukee, then Washington's reserve group accounted for a whopping 62 points (72 percent of the Wizards' total output) during Saturday's shouldn't-have-been-a-nail-biter win in the nation's capital.

For Terry, the man they call JET, this was unexpected turbulence.

"No question, we thought it would be a lot smoother, but, again, it's not as easy as you think a lot of the time," said Terry. "It's good. It's good that we're going through it, and what we're going to do is look back upon this journey and say that we had to go through something. This is definitely challenging. I know for me, myself, I got higher expectations for my performance, but I'll get there."
