TORONTO -- As he looks ahead to the playoffs, Philadelphia guard Andre Miller figures Boston and Cleveland will "most likely" reach the Eastern Conference finals.
The way the 76ers are playing, it's not hard to see why Miller doesn't like his own team's chances.
"You don't want to go on a losing streak around this time of the season, but it's happening," Miller said. "We're playing some good teams and we just can't get the wins."
Miller and Marreese Speights each had 10 points for the 76ers, who have their first five-game losing streak since dropping seven in a row between Jan. 2-14, 2008.
The 76ers have clinched a playoff berth but won't last long if they can't turn things around in their final two regular-season games, which come against the Cavaliers and Celtics. Philadelphia will play host to Boston on Tuesday and visit Cleveland on Wednesday.
The tough schedule will let Philadelphia see how it measures up against the East's top seeds, but Miller has bigger concerns.
"We don't want to measure ourselves right now, we just want to try to figure out how we're going to carry ourselves in the playoffs as a team," Miller said. "It is a measuring stick to a point, but you can't really worry about what those teams are doing. They've accomplished a lot and most likely they'll be in the conference finals. We'll see what happens."
Beforehand, Miller pegged the game as the most important of the season so far for the 76ers, then he didn't deliver, shooting 2-for-14 in 33 minutes.
He wasn't the only Sixer to struggle. Philadelphia coach Tony DiLeo said the whole team took "a step back."
"Overall, I didn't like our chemistry on the court or how we were in synch on the court, both offensively and defensively," DiLeo said. "We weren't on the same page."
Williams said chemistry isn't the 76ers' problem.
"We're 80 games in," Williams said. "If we don't have chemistry by now, this is how we're going to play."
The Sixers are no stranger to slumps: They've had three other four-game losing streaks this season.
"This is kind of familiar territory with this team," Williams said. "We get ourselves in a little bit of a rut and then we come out swinging and we end up winning some games. Losing (five) in a row going into the playoffs may not necessarily be a bad thing for our team."
Leading 81-80 after three quarters, the Raptors opened the fourth with an 8-0 run. Philadelphia couldn't close the gap, and a 7-0 Toronto spurt, capped by Quincy Douby's 3-pointer, gave the Raptors a 102-88 edge with 5:45 remanning.
The 76ers called a timeout, then got two 3-pointers from Iguodala and a pair of free throws from Miller. After Bargnani's dunk, Williams and Miller each made two more from the line, making it 104-100 with 2:51 left.
The Raptors didn't make another field goal the rest of the way, but Bosh, Calderon and Marion went 7-for-8 from the free throw line to help Toronto seal it.
The Raptors have won seven of their past 11, but Bosh doesn't want his teammates feeling like a strong finish redeems a poor start that will see Toronto finish out of the playoffs for the first time in three years.
"Just because we're good on paper right now doesn't mean anything," Bosh said. "It would be a shame and a waste of this season to do the same thing next season."
Philadelphia scored the first five points of the game, but Toronto answered with an 11-2 run and led 27-22 after the first period.
The 76ers went back in front in the second, forcing Toronto to call time out after three consecutive 3-pointers by Royal Ivey gave Philadelphia a 46-39 lead. Marion had four points as the Raptors closed the second quarter on an 8-1 run, tying it at 53 at the break.
- Iguodala's 10 turnovers were a season high.
- Bargnani had a career-high six blocks.
- Toronto finished 18-23 at home. Before the game, Raptors coach Jay Triano said his team needs to show more toughness at home next season. "That has to be something that changes," Triano said. "We have to take care of the home court."
- Bosh thanked fans for their support during a losing season in a pregame address.
- Philadelphia's Reggie Evans was not penalized for throwing the ball into the first row of seats after he was called for traveling in the second quarter.
