Now the TORONTO Raptors are wondering what they would do without him.
The 27-year-old had season bests with 32 points and eight rebounds and equaled his season high with 11 assists on Saturday night as the TORONTO Raptors completed a back-to-back sweep of the New York Knicks with a 115-100 victory.
"Since he's been in the league, I think he's playing at the highest level I've seen," Raptors coach Dwane Casey said. "I remember when he was in Memphis, Houston. He's playing with such force and such confidence and playing the game the right way. He's been playing lights out."
"We shot the ball well tonight, which I thought was a plus," Knicks coach Mike Woodson said. "But we are not going to win consistently until we defend and rebound. I've got to have our bigs in there banging a little bit more and demanding rebounds."
Former Raptors forward Andrea Bargnani, who was booed every time he touched the ball, also scored 12 points for the Knicks but did not play in the fourth quarter because of a stiff neck. Guard Toure' Murry added 11 points.
"I don't have any thought about it," Bargnani said about the reaction to his return to Air Canada Centre.
Casey was impressed with how well Lowry responded when the trade rumors heated up.
"What am I going to do?" Lowry said. "It's my job. I'm not going to be mad. It is what it is. I'm really not worried about it. Until the day comes, I'm going to play for the Raptors and I'm going to play hard."
The Raptors took a 14-point lead into the fourth quarter. Vasquez hit three 3-pointers in the first three minutes of the quarter to give TORONTO a 17-point lead. But Smith made a 3-pointer and Stoudemire scored on a dunk to cut the lead to 101-93 with 4:09 to play.
"It was a five-point play," Woodson said. "With six points down and we get the flagrant and they turn around and make a 3 behind it. That was probably the biggest sequence of the game."
Bargnani said, "We came back, we fought hard. They shot the ball extremely well, they shot like 40-something from 3 (15 of 32 for 46.9 percent), so you have to give TORONTO credit for that. We've got to regroup and get everybody back healthy. That's the most important thing."
The Raptors took a 13-point lead into the second half, but the Knicks cut into that by scoring the first five points of the third quarter. A 3-point shot by Ross put the Raptors into a 14-point lead with 8:25 to play in the quarter. The lead was up to 21 points three minutes later after DeRozan's driving layup. The Raptors led 85-71 after three quarters.
The Knicks took a 34-32 lead on a pull-up jumper by Murry with 6:32 to play in the second quarter. But the Raptors went on a 12-0 run to take a 10-point lead with 4:12 to play and led 57-44 at halftime.
