The Toronto Raptors are on the verge of their best start in 10 years, but they know there's still plenty of room for improvement.
Toronto tries to pick up another victory Wednesday night when it visits the Boston Celtics.
The Raptors (3-1) fell 107-102 at Miami on Sunday before bouncing back with Tuesday's 100-88 win over injury-ravaged Oklahoma City. Toronto was limited to 39.5 percent shooting but found a way to grind it out after scoring 30 points off 21 turnovers.
"It was one of the ugliest wins I've had in Toronto, but we'll take it," backup point guard Greivis Vasquez said. "We have to build, we have to get better -- and we will."
The Raptors are shooting 41.7 percent to rank 25th in the NBA. However, they're seventh in scoring with 104.8 points per game after averaging just over 29 points from the foul line.
"We haven't been playing up to par," Kyle Lowry said. "I know we need to play a lot better. It's just one of those things that we need to fix internally."
Toronto is looking to win four of its first five for the first time since 2004-05. The Raptors have taken four of five from the Celtics, who return home after a winless two-game road trip.
Boston (1-2) fell 104-90 at Houston on Saturday and 118-113 at Dallas on Monday. Jeff Green scored 35 points and Avery Bradley added a career-high 32 as the Celtics cut a 31-point deficit down to one with 39 seconds left.
"We shot ourselves in the foot in the first half the last two games," Green said. "By the end we were out of gas. We can't allow teams to be the aggressor the first 12 minutes. That's what happens."
The Celtics were outscored by a combined 77-41 in the first quarter during their trek before averaging 62.0 points in the second half.
"It's on us. You can't lay down," rookie Marcus Smart said. "It's really frustrating because the second half is the team that we know we can be."
Rajon Rondo had 13 points in last Wednesday's season-opening 121-105 win over Brooklyn before scoring a combined 11 on 5-of-20 shooting in the last two games. He's averaging a league-best 11.7 assists to go with 8.7 rebounds.
The Celtics had outscored the Raptors by an average of 15.2 points during an 11-game home winning streak before falling 99-90 on March 26. Lowry, DeMar DeRozan and Terrence Ross combined for 67 points while Jonas Valanciunas added 15 and 14 rebounds.
"That's a tough team we're running into and a tough place to play," Lowry said.
Toronto may have to get by without Valanciunas, who was forced from Tuesday's win with a facial contusion. The third-year center previously exited to get X-rays on his right hand at the start of the second quarter but returned after no injury was detected.
"He was all messed up," coach Dwane Casey said. "That's part of the NBA, next guy has to be ready to roll."
Valanciunas entered Tuesday averaging 13.7 points and 9.0 boards.
Boston's Jared Sullinger is averaging 20.7 points over a three-game stretch against the Raptors, nearly double his career mark of 10.6.
