After trouncing the Memphis Grizzlies 131-95 at TD Garden on Wednesday, the Boston Celtics are in the midst of a nice break. They don’t play again until Sunday afternoon, when they host the Los Angeles Clippers. The Celtics’ three-day respite is their longest of the season thus far and their biggest until the All-Star Break in mid-February. It couldn’t come at a better time for Boston, which has endured a grueling schedule to start the season. The Celtics kicked off their campaign with 13 games in 22 days, including seven road games and three back-to-backs. The tough schedule may have contributed to their uneven start, as they went 6-7 during that stretch and faltered late in several games. Now, Boston gets a chance to catch its breath and evaluate what’s gone right and wrong over the season’s first few weeks. The Celtics are still working out some kinks after enduring so much roster turnover last offseason, so getting some rest and practice time could help. Fortunately for them, they also have an easy matchup coming up against the Clippers, who have been one of the worst teams in the NBA this year. They’re 3-8 entering play on Friday and have lost six straight games. Story continues below advertisement That’s exactly the kind of team Boston needs to face to build on Wednesday’s win and try to get back to .500. The Celtics follow that up with back-to-back games against the hapless Brooklyn Nets, who have one of the worst records in the league at 1-10. Between the time off and easy opponents, Boston has a great chance to get back on track over the next few days and put its slow start in the rearview mirror.
