RICHMOND, Va. -- After seven months and 28 races, NASCAR has hit that part of the season that really matters. The start of the playoffs signifies a shift in attitude and aggression, and if there was any doubt the mindset had changed, Kevin Harvick posted a warning about his mood for the next 10 weeks.It was a video of an angry bull charging into the grandstands.And so the Chase for the Sprint Cup championship begins Sunday at Chicagoland Speedway with 16 drivers laser-focused on the big prize. Its 10 races, three rounds of elimination, and every man for himself.So dont be surprised if tempers boil over, paint is traded on the track, angry words are exchanged. Its already started, to a degree. Tony Stewart has intentionally wrecked drivers in two consecutive races, including Saturday nights regular-season finale with contact that officially ended Ryan Newmans shot at making the Chase.A frustrated Newman called his former boss bipolar and said Stewart had anger issues. Stewart was nonchalant, said Newman had it coming after running into him three times at Richmond.Remember, the Chase and this format can bring out the worst in even the most mild-mannered driver. Matt Kenseth tackled Brad Keselowski in a very un-Kenseth-like attack in 2014, then he earned a NASCAR suspension last year for an intentional crash that ruined Joey Loganos title chances.Denny Hamlin, who won Saturday night at his home track to give Joe Gibbs Racing three consecutive victories at Richmond and wins in nine of the last 15, said the jockeying for the final spots in the Chase field led to some of the recent aggression. He also speculated the length of the season could be a contributor, especially for drivers not battling for the title.Some guys have a care factor thats really low right now, Hamlin said. I think things get a little bit tamer in the Chase because people are aware of the Chase cars. Whether they say so or not, they definitely race a little bit more careful around those guys, especially when youre not racing for a win.As for the Chase drivers themselves? When the field will be trimmed by four at the end of each round, Hamlin expects to see tense racing.As guys get eliminated, it could definitely ramp back up again, he said.Harvick certainly plans to live up to his word.The 2014 champion, the first winner under the elimination format, has never backed down from anyone or anything. His scathing assessment of his pit crew led to two changes to his race team last week. When he was flagged for speeding on pit road, driver error instead of team error, it could have been seen as a bit of karma working against Harvick for being less than politically correct about his own crew.He doesnt care what it takes, though, he just wants results.You just have to be selfish. You have to do whats best for your team, worry about the consequences when all the dust settles, he said. You have to be narrow-minded, not listen to anything, and do whatever it takes to figure out how to make the best performance. Every point matters. This is a minute-by-minute battle.You just try to think of dotting every I and crossing every T because thats what its all about, and you have to get everything out of every person that touches everything on that car at another level to win this deal.So now its about strategy and how each driver plans to attack each round.For some, like Chris Buescher, just getting into the 16-driver field was the prize. Last years Xfinity Series champion made the Chase by winning a rain-shortened race at Pocono, but he doesnt want to settle for a happy to be here attitude.We look at this first round, and we want to make it past that round. We want to move through the Chase, Buescher said. Then we can re-evaluate from there. If we can keep going farther and improve our program each and every weekend, thats always going to be what were aiming to do.Stewart is also assessing his final Chase appearance before he retires at the end of the year. He slumped his way into the 2011 Chase and said his team didnt even deserve a spot in the field.Then he won the whole thing, his third NASCAR title.So hes just going to play this one by ear.Who knows whats going to happen? he said. All I care about right now is getting ready for Chicago. Once we get through that, Ill worry about Week 2. This is a stressful 10 weeks and you take it one week at a time. Thats what we did in `11, and it worked. Marouane Fellaini Belgium Jersey . The 19-year-old Olsen played 34 games with the Kelowna Rockets of the WHL this season.

Dries Mertens Belgium Jersey . -- Vincent Lecavalier got everything but the desired result in his return to Tampa Bay. Jan Vertonghen Belgium Jersey . -- The St. Johns IceCaps weathered a wild first period with the help of goaltender Jussi Olkinuora, before finding offensive inroads in the second. BOSTON -- The Boston Celtics, still looking to have their entire team on the floor in the same game, host the road-weary Denver Nuggets on Sunday night.The Celtics (3-2) played the first three games of the season without the injured Marcus Smart and Kelly Olynyk, then got Smart back but lost Al Horford to a concussion prior to Wednesdays home win. In that game, Jae Crowder went down with a left ankle sprain.Olynyk appears to be the closest to returning, from offseason shoulder surgery. He has officially been listed as questionable for Sunday nights game.Id say hes closer than further, so well see, coach Brad Stevens said Saturday. Hes going to be listed as questionable, but thats going to be completely his and (trainer Ed Lacertes) call. But hes getting a lot better ... hes right around the corner here.Olynyk practiced with the Maine Red Claws, the Celtics D-League team, Friday.Meanwhile, Horford had progressed to jogging on a treadmill and doing some on-court work and the swelling was down in Crowders ankle.Als getting better, Stevens said. He did a little bit of activity, as you probably saw above. Hes going to be out on the court a little bit today, but hell be out tomorrow (against the Nuggets). If everything goes well today then well up his activity tomorrow but he will not be cleared to play by game time, is what Ive been told.The Nuggets (2-3) are 1-2 on their current five-game road trip that will give them six of their first seven games away from home.Saturday night in Detroit, they fell behind 10-0 and werre down 29-12 at the end of the first quarter and never caught up.dddddddddddd Sunday, they face a team playing on its home floor and one that hasnt played since losing in Cleveland Thursday night -- and will do it with a different starting lineup.Im just tired of watching the struggle that goes on out there, said coach Michael Malone. It almost looks like theyre disinterested to start the game and if were going to go down, were not going to go down like that.Our defense was horrendous tonight. They did whatever they wanted. Its the fifth game in a row where the squad came out asleep, so were not going to have the same starting lineup tomorrow night. We cant afford to keep building ourselves 15-20 point deficits to start the game and play catchup. That group is unable to change that, so well try to mix up the lineup to give ourselves a better chance at playing 48 minutes because Im tired of watching that.Before the game, Malone said, Regardless of who we play, our goal is to play with pace for 48 (minutes), whether its Minnesota or Boston tomorrow night. We have to be true to ourselves and play our style of basketball.Clearly, that didnt happen Saturday night.The Nuggets got Gary Harris (groin) back Saturday, but Will Barton remained out with a sprained ankle.The Celtics have swept the two-game season series from the Nuggets each of the last two seasons and are 5-1 over the last three.
