For the third time in four years, Shaquille O’Neal is on the move, rumbling across the N.B.A. landscape, forcing adjustments, reassessments and revisions from coast to coast.The Cleveland Cavaliers, in a bold stroke aimed at winning the championship, acquired O’Neal from the Phoenix Suns, in a multiplayer trade that will have ramifications across the league.O’Neal, a 15-time All-Star, will join LeBron James, the league’s reigning most valuable player, to form one of the most powerful tandems in the league. The Cavaliers were already an elite team — winning an N.B.A.-best 66 games last season — but one that was missing any star power, or reliable scoring, beyond James.That will no longer be a problem. Even at 37, O’Neal remains a fearsome threat in the low post. He averaged 17.8 points and 8.4 rebounds for the Suns last season, played in 75 games — his highest total in four years — and was named to the all-N.B.A. third team.With O’Neal, Cleveland now has an answer to Orlando’s Dwight Howard, who bulldozed through the Cavaliers in the Eastern Conference finals.James’s championship dreams were crushed in Game 6 of that series, and he left the arena in a deep funk, without congratulating the Magic or speaking to the news media.The depression that settled over Cleveland in late May has now cleared.The Suns and Cavaliers had been discussing parameters of a deal since before the February trading deadline. At the time, it was deemed too great a risk by the Cavaliers, given their dominant season and their enviable chemistry. What appeared like a gamble then looks essential now.Although the Suns initially held out for a better package, they settled for a deal that gives them financial relief, and little else. Phoenix will receive two marginal rotation players, the past-his-prime center Ben Wallace and the swingman Sasha Pavlovic, plus $500,000 and a future second-round pick.If the Suns waive Pavlovic, whose contract is only partially guaranteed, they can save around $9 million in salary and luxury-tax payments. They could save millions more if Wallace decides to retire and accept a buyout, a possibility he has entertained. SOURCE:NYTIMES.COM
