Even after his team's latest win, Raptors coach Dwane Casey was looking for more from his players.
Kyle Lowry scored 10 of his 25 points in the fourth quarter and DeMar DeRozan added 19 to lead Toronto to a 108-95 victory over the Philadelphia 76ers on Saturday night.
"There are areas we need to improve," Casey said. "For where we're trying to get to, it's not just to win but we've got to continue to improve because we have bigger fish to fry. I'm the only Debbie Downer in the group."
Jonas Valanciunas had 17 points for the Atlantic Division leaders, who will go for their fourth straight victory when they wrap up a six-game road trip against Orlando on Thursday in London.
Casey thinks the trip overseas is a perfect opportunity for some fine-tuning.
"Hopefully, we'll use this trip to England as a mini training camp sort of situation," he said. "We have a lot of things to get better."
The 76ers thought the Raptors were plenty good.
"That might be a deep playoff team," Philadelphia coach Brett Brown said.
Ish Smith scored a career-high 28 points and rookie Jahlil Okafor had 19 for Philadelphia, which dropped to 4-35. The 76ers have lost 11 straight games to Toronto.
"We were too far behind the 8-ball and they just kept punishing us," Smith said.
Toronto led by as many as 15 in the third quarter before the 76ers used a 9-0 run over the final 4:17 to close to 75-69 entering the fourth.
Lowry had the first six points of a 9-4 Toronto spurt to open the final period, capped by Patrick Patterson's 3-pointer with 8:47 remaining, that pushed the Raptors' lead back to 84-73.
The 76ers never threatened from that point.
Philadelphia scored the game's first 12 points as the Raptors missed their first seven field goal attempts.
The Sixers' advantage was 38-34 after Isaiah Canaan drained a pair of 3-pointers within 9 seconds of each other, both on assists from T.J. McConnell, with 6:48 remaining in the first half. But consecutive highlight-reel dunks by DeRozan started the Raptors on a 23-6 run to close the half, giving Toronto a 57-44 lead at the break.
DeRozan first dunked over Okafor with force before finishing a reverse alley-oop after a pass from Lowry.
