With all the injuries that seem to be piling up for the Boston Celtics, their bench has been called upon to carry more of the load.

No problem.

Boston’s backups have been delivering first-rate results all season. The Bucks -- 99-83 losers to the Celtics on Tuesday night at Milwaukee -- are the latest foe to fall at the feet of the Celtics’ reserves.

“It’s all about the consistency from the starters to the bench guys,” the Celtics’ David Lee told Comcast SportsNet’s Abby Chin following the win. “Everybody is starting to get into a rhythm now.”

Usually the Celtics’ bench does damage just to the opposing team.

But Tuesday was a game in which they not only outscored their Milwaukee bench brethren (50-25), they also wound up outscoring the Celtics’ starters (50-49).

“Try to go out there and make the team better,” said Kelly Olynyk who had 11 points off the Celtics bench. “Whether it’s defensively, offensively, just get the team over the hump. That’s what our second group has done the last couple games. And that’s what we need to do in order to be a good team.”

Indeed, it’s not just their offense that’s getting the job done.

Along with averaging a league-best 51.0 points per game off the bench this season, the Celtics are also giving up 29.3 points which is the fourth-fewest bench points allowed thus far this season.

Olynyk has the lowest defensive rating (72.9) among NBA players to average at least 15 minutes on the floor this season. Teammate Evan Turner (85.1, 8th overall) is also ranked among the top 10. Boston also has two others - David Lee (88.1, 17th overall) and Marcus Smart (88.6, 19th overall) - ranked in the top 20.

And in Tuesday’s win, four of five lowest defensive ratings (Turner, R.J. Hunter, Olynyk and Jonas Jerebko) were registered by players off the Celtics bench.

So when it comes to offering up praise following victory, it was indeed a team effort that was fueled in large part by the second unit.

“That was a good team win,” said Celtics head coach Brad Stevens who then added, “the bench was good again.”
