The Suns lost in their bid for superstar power forward LaMarcus Aldridge, but they improved their fortunes nevertheless by acquiring veteran center Tyson Chandler to go along with 22-year-old former University of Maryland center Alex Len. Both at 7-1, the two complement each other in that they are good defenders, Chandler one of the best big-man defenders in the NBA. Signed to a four-year $52 million contract by the Suns, Chandler anchored the Dallas Mavericks defense last year, averaging 11.5 rebounds a game, in addition to having the second best field goal percentage in the league at 67 percent. He's somebody coach Jeff Hornacek's Suns team long has needed: a center who can score in the paint, as attested to by his 147 dunks, third best in the league. Published reports say Len, who has turned out to be one of the best young centers in the NBA, is happy that he will be mentored by the veteran. In his second year as a pro, Len emerged in the second half of last season as the Suns' starting center, averaging 6.6 points and 6.6 rebounds in 22 minutes per game, but he still shared big playing time with two other big men. Combining Chandler's other attributes with his 10 points per game, the two should be one of the league's best one-two punches.
