Think the Western Conference-leading San Antonio Spurs are sitting at home trembling in fear after watching the first half of this mess? The Spurs play host to the Lakers on Tuesday. The Heat won the 3-on-3 game handily, with Chris Bosh scoring 18 points, LeBron James scoring 11 and Dwyane Wade getting 10. The Lakers’ big three are stinking up the joint so far. Kobe Bryant had eight points on 3-for-10 shooting, plus a technical foul. Lamar Odom had eight points. Pau Gasol had 11 on 3-for-11 shooting. Let’s see if Bryant’s block of Wade’s last-second try does anything to get the Lakers going in the second half. They started fine, then settled into an ineffective funk that produced their first-half deficit.
