Celtics end Cavaliers’ 15-0 start to the season in NBA Cup matchup
Associated PressBOSTON — This one wasn’t about their perfect season or a 15-game winning streak or even the NBA Cup. “This was a great test for us, and unfortunately we didn’t get the win,” said Donovan Mitchell, whose 35 points couldn’t prevent the Cavaliers from picking up their first loss of the season, 120-117 to the Boston Celtics on Tuesday night. “It’s definitely a measuring stick,” said Mitchell, who scored 18 points in the fourth quarter, including 14 straight Cleveland points in the final four minutes. You want to see where you’re at, but not hold too much weight on it.. We’re not going to be the same team now that we are in April.” The Celtics won an unprecedented 18th championship last spring -- rolling over the Cavaliers in five games in the Eastern Conference semis – and entered the season as the favorites to repeat, or at least make it back to the NBA Finals. “But, like I said, there’s no championships in November.” The Celtics used a 3-point barrage on Tuesday night to open a 21-point lead, then watched as the Cavs cut it to two in the third quarter.
