"That's why we love him".
DeMar DeRozan led Toronto with 37 points while Jonas Valanciunas added 19 points and eight rebounds, with Norman Powell chipping in with 13 points and Serge Ibaka scoring 12.
The Cavaliers have a chance to complete a series sweep in Game 4 Sunday afternoon at the Air Canada Centre.
"The reason we are the team we are is because of Kyle", DeRozan said.
Raptors coach Dwane Casey said his players should use James's behaviour as motivation. "It's about pride", Casey said. They ended up with a 115-94 victory to go up 3-0 in the series.
Cleveland Cavaliers, last year's NBA Champions now lead their Eastern Conference Semi-Finals against the Raptors 3-0.
Irving scored 16 points and Kyle Korver had 14 for the Cavaliers, who have posted three straight double-digit wins over Toronto.
Kawhi Leonard and LaMarcus Aldridge both registered 26 points in the 103-92 success. "Being down, being resilient, giving everything we got, and just fighting".

All-Star point guard Kyle Lowry says he's doubtful to play for Toronto on Sunday in Game 4 of the Raptors' Eastern Conference semifinal series against the Cleveland Cavaliers. He worked out a few hours before Friday's game and was on the court during warmups but limped back to the locker room before the national anthems. "He was limping badly". "He was in so much pain he just couldn't go". "The medical people know the severity his ankle". Lowry or whoever is running point needs to do a better job creating and Toronto needs to look to make the extra pass to get more open shots.
When it came to defending the three-point shot, Cleveland was especially effective, holding Toronto to 2-of-18 from long-range.
Lowry made it clear James is in no way "breaking spirits" with his dominant play, but simply believes we're watching one of the greatest players in National Basketball Association history at work right now. But when James dialed up a 3-pointer with 6:49 left in the game, the Cavs were ahead 95-80.
"That stretch right at the beginning of the fourth quarter is what got us", Casey said. He scored 21 points in the first half, hitting 7 of 12 from the field and all seven of his free throw attempts.
Raptors: Joseph started for the first time in 70 playoff appearances.
LeBron James was again dominant with 35 points, eight rebounds and seven assists. It was the first time Toronto had lost three straight games since February.
LeBron James' sensational form in the NBA Playoffs has continued with a 35-point haul against Toronto on Friday night. "I hope he is able to go (Sunday) but if he is not it's a great opportunity for Cory (Joseph) to step in and play". In the series, Cleveland has outscored Toronto 135-51 from beyond the arc in this series.
DeRozan attacking the defensive strategy by splitting the double-teams or moving before the trap arrived.
Percentages: FG.513, FT.857. Trailing by one late in the third, Kevin Love hit a jumper to put Cleveland ahead. He also went 13-for-13 on free throws.
Percentages: FG.437, FT.941.
