"It's the little things right now that are separating us from wins and losses," he added.
Health is also a factor for the reeling Knicks. Already missing guards Raymond Felton (right groin) and Pablo Prigioni (right foot), New York again played without leading scorer Carmelo Anthony, who sat out for the third straight game with a sore left ankle. Also absent was Metta World Peace (left knee), who sat out for the fourth time in five games.
Woodson said he hoped to have Anthony back when the Knicks make a three-game swing next week through Texas, where they also play Houston and Dallas.
"It's hard to replace 30 points a night but we need to," Smith said.
New York almost made a game of it late, but its comeback bid was halted by a costly foul. Lowry made two free throws to put Toronto up 100-86 with 5:49 left, but Smith scored five points and Stoudemire had a driving dunk to cut it to 101-93 with 4:12 remaining, when Casey called a timeout.
Toure Murry of the Knicks was called for a flagrant foul after sending Lowry sprawling with 3:25 to go. Lowry made both free throws and then knocked down Toronto's 14th 3-pointer, putting the Raptors up 106-95 with 3:13 left.
Woodson called it "the biggest sequence of the game."
"I thought (Murry) got pushed off but he ended up grabbing and tripping the guy and they called a flagrant," Woodson said.
Lowry scored nine points in the first quarter and DeRozan had seven, two on a baseline dunk, as the Raptors took a 26-22 lead after one.
Ross scored 11 points in the second, making three 3-pointers and throwing down an eye-popping dunk, as the Raptors used an 18-5 run to extend their lead. Toronto made 10 of 20 field goal attempts in the second and led 57-44 at halftime.
Ross made three more 3s in the third and Lowry had eight points as Toronto took an 85-71 advantage into the fourth.
NOTES: Anthony did not travel to Toronto, remaining behind in New York for treatment. An update on his condition is expected Monday. The Knicks will likely take Sunday off after playing back-to-back games against the Raptors. ... Lowry also had 11 assists in Friday's win at New York. ... Chandler picked up a technical foul for arguing a traveling call in the first quarter.
