The Mavericks led 85-55 late in the third quarter before the Raptors mounted their franchise-record comeback and won 110-107 at Scotiabank Arena in Toronto.
"We had a great team effort," Lowry told reporters. "Malcolm [Miller], Terence Davis, Rondae [Hollis-Jefferson] and Chris Boucher, I give them all the credit today. They won that game for us. ... Give those guys the credit."
Toronto went on a 9-2 run at the start of the fourth quarter and a 13-0 run before tying the score 95-95 with 5:30 remaining.
Lowry scored a game-high 32 points and had 10 assists and eight rebounds in the win. Chris Boucher scored 21 points and had seven rebounds and four blocks off the bench for Toronto. Jalen Brunson paced the Mavericks with 21 points.
"[Lowry] was unbelievable," Nurse said. "He really didn't have a good game going until [late].
"Then he started firing and making and driving ... he was doing it all. Not sure I've seen anything like that."
