The Lakers appear to be only a few quick dribbles away from Showtime after acquiring Steve Nash. The team's championship fortunes substantially improved after turning the point guard position into one of its biggest weaknesses to one of its biggest strengths. The excitement stemming from last week's sign-and-trade with the Phoenix Suns will continue at noon Wednesday when Nash is officially introduced as a Laker before a news conference at the team's practice facility in El Segundo. But underneath the glitz and the glamour regarding Nash's arrival, an unsettling reality still holds true: The Lakers can't defend quick point guards. Nash used to play for the Phoenix Suns, which adopted the famed "seven seconds or less" brand of basketball. He ranks 147th overall in total defense, which isn't much better than Derek Fisher (166th). The Lakers can overcome that, though.
