Irving looked completely flummoxed by the Spaniard, who threw him completely off kilter at both ends of the floor.
Irving looked perplexed after Calderon took a charge under the Toronto net midway through the third quarter, summing up his evening.
Calderon said his lingering hamstring issues are not bothering him at the moment and that has made a big difference in his play, which has been criticized over the past two seasons.
"Everybody knows my (injury) problems," Calderon said.
"I'm good, feeling great and you don't forget about how to play basketball."
Irving shot 2-for-12 for six points in the season opener versus Calderon's tidy 15 point, 11-assist effort. This time around, Calderon filled up the stat-sheet (13 points, 11 assists, six rebounds), while Irving again started 2-for-12 from the floor and finished 3-for-13. Irving had shot 21-40 over his previous three games.
Speaking of top picks, another oft-maligned Raptor, Bargnani, continues to sizzle under the direction of Casey.
The Cavs looked lost trying to defend the swift 7-footer. Whether nailing from deep repeatedly or faking veterans Antawn Jamison and Ryan Hollins out of their sneakers, Bargnani was cooking.
How well is Bargnani playing this season -- for the first time ever and the first time since Chris Bosh was in town, a smattering of possibly well-lubricated fans were chanting M-V-P when Bargnani went to the line.
MVP? Let's not get crazy, people, but Bargnani certainly has played at an elite level so far.
The coach singled out Bargnani for -- of all things -- his defence, particularly his ability to cover enough ground to make the defence effective.
He's playing at an all-star level," Casey said.
"I've been around some great players: Shawn Kemp, Gary Payton, Kevin Garnett, Dirk (Nowitzki), he's playing at that level offensively and defensively."
Bargnani has averaged 27.5 points per game over his past four games.
The Raptors were also buoyed by the play of DeRozan, who continues to emerge as a completely different player.
DeRozan hit two ridiculous three-pointers in the first half, including one in the final seconds from a few steps past halfcourt, to help the Raptors claim a seven point advantage heading into the break.
DeRozan has now nailed 10 three-pointers on the season after hitting only nine - total - over his first two NBA campaigns.
With officials thus far refusing to give DeRozan the benefit of many calls for his forays to the hoop, the shooting guard has taken matters into his own hands, drilling shots from all over the court.
Toronto turned Brampton's Tristan Thompson into a non-factor (one point, three rebounds and a blocked shot).
Thompson said he didn't feel any extra pressure.
"My job is to play basketball. There was definitely no distractions," Thompson said.
After a rough couple of games, Raptors sophomore Ed Davis rebounded with a strong outing.
The game was the first in a brutal stretch for the Raptors who will play eight times in 11 nights -- including a back-to-back-to-back.
