TORONTO -- A half-time message woke up the Raptors on a night when Toronto found itself sleepwalking against the struggling Detroit Pistons. Custom Buffalo Bills Jerseys . "We pretty much said, This is a must-win game," Amir Johnson said after Toronto trailed Detroit by four at the break but finished with a 112-91 win Wednesday. "We had to go out and take it. We did that." After Johnson and DeMar DeRozan started the game cold, their teammates kept things close and allowed a second-half turnaround to take place. Jonas Valanciunas had 16 points and 11 rebounds while Kyle Lowry scored 21 points and added nine assists in a game the Raptors needed to work themselves into. "The first half was a little sluggish but we picked it up and thats most important," said Lowry. "Thats a team. You need everybody, all 15 guys and all 13 that are dressed to step up and take advantage when the opportunity comes." Toronto (17-17) needed strong performances from Valanciunas and Lowry. DeRozan and Johnson combined to shoot 0 for 16 from the floor in the first half with the team making just 33 per cent of their field goals compared to 47 per cent shooting from the Pistons. Brandon Jennings led the way for Detroit (14-22), scoring 22 points to go with nine assists in the loss. Andre Drummond added 16 rebounds as the Pistons lost their sixth straight. After going up 11 midway through the second quarter, the Raptors went more than five minutes without a field goal and allowed Detroit to go on a 14-0 run to take a 54-50 lead at the half. "We started off terrible," DeRozan said. "We didnt have any legs and we told ourselves that we can have no excuses. We had to pick it up because that wasnt us in the first half." Things flipped in the third quarter when the Raptors outscored Detroit 34-20 while making 11 of their 22 field-goal attempts. DeRozan and Johnson were able to shake off their starts to help Toronto build a 10-point advantage going into the fourth. "There was a big difference," Toronto head coach Dwane Casey said of the two halves. "We knew it was going to be a grind out game and thats something we are learning to do, to grind things out possession by possession, quarter by quarter. "We knew DeMar and Amir werent going to go zero-for, in the second half. The defensive intensity (after halftime) is what changed the game." The final quarter resembled the third as Toronto outplayed the Pistons and broke the game open with five minutes remaining and the lead up to 18. All five of Torontos starters finished the game in double figures after the team dropped its last two contests against the Miami Heat and Indiana Pacers. DeRozan finished the game shooting just 3 for 15 from the floor, but connected on 13 of his 16 free-throw attempts to finish the game with 19 points. The 16 free throws tied a career-high. "He went to plan B and thats what hes got to do," Casey said about DeRozans night. "About a year or two ago he wouldnt have done that. He did a good job of attacking the feet and taking what the defence gave him." Johnson finished the game with 10 points and 11 rebounds and Terrance Ross scored 17 points. "Hes improving as a basketball player," Lowry said of Rosss evolving game. "Catching and shooting, his confidence is unbelievable. Hes showing his versatility. He can play defence. Hes scoring, but if you look at the defensive assignments hes had in the past few weeks, hes done a great job at it ... I know I tip my hat to him." Lowrys explanation for the strides Ross has taken was simple -- hes playing more. "Thats how you get better," he said. "Once you get more minutes, more repetition, thats how you get better." Toronto finished the game shooting 41 per cent from the floor as compared to 40 per cent for the Pistons, but the Raptors shot 91 per cent from the free-throw line, making 31 of their 34 attempts. Detroit made just 19-for-35 shots from the line. Notes: Torontos Tyler Hansbrough missed his fourth straight game with a left ankle sprain. ...

Cammalleri suffered a concussion in the Flames 2-1 loss to the Pittsburgh Penguins on Saturday. The 31-year-old forward did not travel with the team to Carolina.Ronny Deila says his inability to improve Celtic during his time at the club has killed him inside. The Norwegian, who took over from Neil Lennon in the summer of 2014, announced he was leaving in the summer just three days after the Scottish Cup semi-final defeat to Rangers.Deila led the club to the Scottish Premiership and League Cup double in his first year and the Hoops currently boast an eight-point lead over Aberdeen with five games remaining. Speaking ahead of the first post-split fixture against Ross County on Sunday, the former Stromsgodset manager said: It has been a tough week, there has been a lot of thinking and it hasnt started this week either.I have been thinking about this for a while because I havent felt the team has got the results they should have and, maybe more importantly, the performance and improvement I wanted.When I came in to the job, I talked about improving the team and playing attractive football and I think the last six months we havent had the improvement that we need. Ronny Deila says a lack of improvement at Celtic in the last six months was key to his decision to leave the club And with the speculation on his future with the club now over, Deila admits he is looking forward to bowing out with a second successive league championship.Improvement is one of my biggest values and when you dont get it, it kills me inside and I lose energy with that.I dont think there has been a lot of improvement and when you dont get improvement, the outside pressure is going to get harder and harder as well. Celtic have not improved in the manner Deila had hoped I have no problem dealing with that, I have been sitting in this room a lot of times and there has been a lot of difficult questions.That is not the problem, the problem is when you dont get improvements and tthe things you said you wanted to create when you came in the door, you havent created. Buffalo Bills Jerseys. One of the reasons we havent had that improvement is because of the pressure and speculation around me all the time. Celtic won the title in Deilas first season in charge That is why I think it is best for the club that new energy is coming into the club next season and now we can really focus on winning the five games and getting five-in-a-row. It is going to be a huge thing for me, the players and the whole club, this is why the decision has been made.And Deila has rubbished suggestions he was not in charge of the clubs transfer policy during his near two-year spell at the helm, insisting he takes full responsibility for the current strength of the squad.One, I signed the players so dont think about that. There is not one player here that I havent said yes to. Two, I knew what I went into when I took the job, said Deila, who brought 22 players to the club during his 22 months in charge. Erik Sviatchenko, one of Deilas last signings for Celtic This club want to be drifted in a positive way and have a positive economy and you have to drift in those circumstances.Everything that is coming into the club is going out of this club. That was said before I came here and its the same now. It is the philosophy of the club and I think its a very, very good thing. I have had good communications with the club and Peter [Lawwell]. I am not a bitter man. I was given a chance but I felt that lately we havent had the development that we wanted in the team.
