The Dallas Mavericks made a bold move to upgrade their backcourt, an indication that they expect to challenge for the NBA title this season, though its not a move without risk. Garrett Grayson Jersey . Numbers Game breaks down the Rajon Rondo trade. The Mavericks Get: PG Rajon Rondo and PF Dwight Powell. Rondo, 28, is a pass-first point guard who has averaged a league-leading 11.0 assists per game since the start of the 2010-2011 season and leads the league this season with 10.8 assists (and 76.1 total passes) per game. As a shooter, Rondo is abysmal. He can penetrate and get to the rim, though he has not been as effective driving the ball to the basket this season, averging 6.6 drives per game, compared to 9.5 per game last season. Rondos inability to hit jump shots makes it easy for defenders to give him more room on the perimeter and his horrific free-throw shooting -- hes hitting a career-low 33.3% from the line this year -- doesnt offer much reason to do anything but get physical with him when he attempts to get near the basket. At his best, Rondo can be a tenacious defender, with long arms which help him steal the ball and hes an exceptional rebounder, averaging a career-high 7.5 rebounds per game this season, but hes also run into injury problems, playing 143 of a possible 252 games since the start of the 2011-2012 season. In Dallas, a healthy Rondo should be an asset. He doesnt need to shoot often, as the Mavericks have Dirk Nowitzki, Monta Ellis and Chandler Parsons ready and willing to fire away, and Rondos other skills -- most notably ball distribution and rebounding -- will be clear upgrades for the Mavericks. Rondo makes a little less than $12-million this season and will be a free agent at seasons end. Powell is 23-year-old rookie from Toronto, who played four years at Stanford and was a second-round pick by Charlotte in the summer; he has since been traded to Cleveland, Boston and now Dallas. Thats a lot of different franchises in a short period of time as a pro, and hes only played nine minutes in the NBA this season, but the athletic 6-foot-11 forward did put up 21.5 points and 10.5 rebounds per game in four games in the D-League. It might be a stretch to imagine Powell playing any kind of role for a contending Mavericks team this season, but they are a little thin in the frontcourt, so its not out of the question that Powell could see some action. Powells contract runs through next season, and pays $507,336 this season then $845,059 next season. The Celtics Get: PF/C Brandan Wright, PG Jameer Nelson, SF Jae Crowder, a conditional first-round pick in 2015 and second-round pick in 2016. Wright, 27, had found a niche as an extremely efficient big off the bench for Dallas, shooting a league-best 69.7% from the field since the start of last season. The 6-foot-9 power forward shoots such a high percentage because he rarely bothers to shoot from beyond 15 feet, and does most of his damage close to the basket. In Boston, Wright should fit into the Celtics big-man rotation with Kelly Olynyk and Jared Sullinger. Making $5-million this season, Wright will be a free agent at seasons end. Nelson is a 32-year-old point guard that had trouble adjusting to Dallas, scoring a career-low 7.3 points per game while shooting a career-low 37.4% from the field. Earlier in his career, Nelson could penetrate and get close to the basket more regularly but, whether its age, his role in the Mavericks offence or some combination of the two, Nelson was rarely getting to the rim and his shooting percentage suffered as a result. In the first year of a two-year, $5.5-million deal, Nelson can fit into the Celtics rotation, but it does appear that hes in decline, so not much more than a stopgap solution for a team that hopes to get better. 24-year-old Crowder has been a back-of-the-rotation player, playing 10 minutes per game this season, averaging 3.6 points and 1.2 rebounds per game, shooting 43.4% from the field and 34.2% on threes. Hes making $915,243 this season and will be a restricted free agent at the end of the season, but can fill a role as an inexpensive wing defender. Boston also received a conditional first-round pick in 2015 and a second-round pick in 2016. Any pick from the Mavericks is likely to fall in the bottom third of the round; looking at picks 21-30 from 2004 through 2013, there were an average of just under two picks per year in that range that turned into NBA starters, but about six in 10 were multi-year rotation players, so there is some value to a late first-round pick, but hitting a home run (like Rondo, Kyle Lowry or Kenneth Faried) is rare. On top of all that, the Celtics have a $12.9-million trade exception available to them when looking to make further moves. Verdict: The Mavericks have an opportunity to compete for a championship this season and Rondo gives them a guard that can go head-to-head with the other quality point guards in the Western Conference. If, for whatever reason, it doesnt work, the cost wasnt really prohibitive -- some pieces that can be helpful, but no shooting stars going the other way.

After deputy commissioner Bill Daly said the league would consider pulling out of Sochi if something "significant" happens before players arrive, those set to participate are trying not to worry about that scenario. "Between the NHL and the NHLPA and the Olympic people, in communication obviously with the people in Russia, theyre going to advise us if we shouldnt go," Ken Holland of Canadas management team said Tuesday. "Im looking at the lead of the NHL. "Until they tell us were not going, Im going to Newark and going to jump on a plane and go to Sochi." A Hockey Canada spokesman said the organization had no official comment, adding nothing has changed about the situation. Charter planes are scheduled to leave for Sochi on Feb. 9, two days after the opening ceremony. Security concerns are keeping athletes on edge well before that, though Daly said in an email to the Associated Press he doesnt expect the plan to change. "Obviously, if something significant were to transpire between now and February 9 that causes us to question that conclusion, we will re-evaluate," Daly told the AP. Forward Tomas Tatar, who will represent Slovakia, read about that Tuesday morning before the Detroit Red Wings morning skate. "There would (have to) be a good reason if something happens before," Tatar said. "Obviously that would be not everythings OK there, so I would probably agree with the people here — why we should go there if something is not good? Hopefully nothing will happen and I think everythings in good hands." Olympic teammate Andrej Meszaros, a defenceman for the Philadelphia Flyers, said that possibility is in the back of his mind even if he doesnt want it to be. "It would be disappointing, thats for sure, but safety first," Meszaros said. "Theres nothing you can do about it. "Unfortunately, the world is like it is with the threats and theres nothing you can do about it. People are (ticked) off. Well see what happens in the next few days." Mark Streit, who represented Switzerland in Salt Lake City in 2002, Turin in 2006 and Vancouver in 2010, is trying to keep his focus on the Flyers upcoming schedule and not the off-chance NHL players wont go to Sochi. "Thhe NHL will do what they think is the best for the players and for our safety and for the families safety," Streit said. Ito Smith Falcons Jersey. "Thats out of (our) control. Im not really worried about that." Jimmy Howard, whos expected to be the third U.S. goaltender, is more worried about bouncing back from another knee injury. He insisted hes not thinking about Olympic contingency plans or security concerns. "Im trying not to let that consume me,"Howard said. "I look at it as this could be possibly a once-in-a-lifetime opportunity. "Im hoping everything goes off without a hitch." U.S. forward James van Riemsdyk said after the Maple Leafs morning skate in Toronto on Tuesday he doesnt have any family members going and that its tough not to wonder about the safety of athletes in Sochi. "Theyve reassured us that theyre taking a lot of measures over there," van Riemsdyk said. "All the players want to play, thats not really the issue here. Safety is the No. 1 priority." Jakub Voracek of the Czech Republic is hoping the Russian government has spent enough money to keep everyone safe. "I think the security, its very tight there," the Flyers winger said. "Obviously its going to be a pain, probably, for the people that want to watch the games or something. But its what you got to do. "In todays world you never know what happens. You go into the mall right here and theres a shooting. You go to the movie theatre, you get shot. A lot of crazy people running around in the world today. Its not only in Russia. Youve got to make sure that the securitys very tight." While Howard hopes these are just "empty threats" against the Olympics, Holland recalled similar concerns going into Vancouver. Political concerns in that region of Russia have made this seem like a more dangerous situation. "I think in this world we live in today, unfortunately there are times that you always have concern," Holland said. "But you have to trust that the people that are in charge of security are going to be on top of things." The Players Association said in a statement "the NHLPA continues to be in contact with Olympic and security officials regarding plans for the Olympic Games in Sochi, and will work closely with all concerned to monitor matters in advance of and during the Games."
