TORONTO — DeMar DeRozan remembers the angry emotions Raptors teammate Bismack Biyombo once stirred in him as an opponent.

“I hated him,” DeRozan said Sunday.

The Cavaliers likely feel a little anger toward Biyombo after his pivotal performance Saturday, when he helped stop the their 10-0 start to the playoffs in the Raptors' 99-84 victory in Game 3 of the Eastern Conference finals. Game 4 is Monday night at Air Canada Centre.

Biyombo hauled down a Raptors' playoff-record 26 rebounds, blocked four shots, and scored six of his seven points in a quick fourth-quarter spurt that helped seal the win.

That wasn't all. Biyombo was involved in a first-half skirmish that saw LeBron James take a tumble after catching an accidental elbow from his own teammate, Tristan Thompson. Late in the fourth, Biyombo drew a flagrant foul after he collared a driving James, sending the Cavs star sprawling again.

DeRozan hasn't forgotten what all that feels like.

“I hated Biz,” the Raptors' All-Star guard said. “He was a fouler, always blocking shots … always went for the pump fake, though, but I hated Biz. Now he's one of my favorite teammates of all-time.”

Raptors coach Dwane Casey understands Biyombo can be a “nightmare” and a “nuisance” to play against, whether it's the center's habit of finger-wagging after blocks, or flexing his muscles after dunks.

To Biyombo, being a nuisance is no big deal. It's the way it's got to be.

“Until you really get to know the real side of me, then you know who I am,” he said. “But on the floor I don't have friends.”

At the final buzzer Saturday, Biyombo lay crumpled in pain in the Cavaliers paint after being struck below the belt while battling Dahntay Jones for a loose ball. Biyombo took the hit while tapping the ball to a teammate, his eighth offensive rebound of the night.

Casey was upset at the referees after the game, complaining that Biyombo wasn't getting calls and citing the Cavaliers' 86-51 edge in free throw attempts in the series.

“I'm not trying to get anybody,” Casey said. “It's over with. I said what I had to say last night.”

Jones was suspended by the league for Game 4, and Casey was fined $25,000 for criticizing the officials.

After a testy, physical Game 3, Cavaliers coach Tyronn Lue and some players also were wondering whether they were getting a fair shake from the referees.

But James didn't want to say whether he's getting the whistles he deserves.

“I really don't get involved too much,” he said. “I just let the referees decide what the call may be.”
