After watching Marc Gasol improve last season, Memphis guard Greivis Vasquez believes his teammate can become the NBA's best center. And after the first-round series against San Antonio last season, Gregg Popovich and the Spurs probably would agree. Gasol ripped the Spurs for averages of 14.1 points and 12.3 rebounds in the Grizzlies' stunning six-game series upset in the first round last season. The 7-foot-1 Spaniard shot 53.3 percent in the series from the field against San Antonio, including 67.6 percent in the four games that the Grizzlies won in the series. Once the lockout is over, the Grizzlies biggest immediate priority will be to sign Gasol. Greivis calls him "a very key player on our team."
