A razor-thin San Antonio Spurs victory. Followed by a Miami Heat blowout victory. Followed by an even-bigger Spurs rout. "It's like bipolar basketball at times," Heat center Chris Bosh said Wednesday of this NBA Finals series that turns to its Game 4 chapter Thursday at the AT&T Center, with the Spurs holding a 2-1 lead. Confounding? You bet. So confounding it had Heat forward Shane Battier waxing on the "psychosis of what goes on in a road game" before Wednesday's practice. While Bosh and Battier took a more erudite approach to where this series stands, teammates for the most part were basic and blunt when it came to the 113-77 Tuesday Game 3 loss that delivered the Heat to this deficit: They not only didn't play well, they didn't play hard enough. "We didn't give the second, we didn't give the third, we didn't give the fourth effort," forward Udonis Haslem said. That led to video reflection and soul searching Wednesday. "I like pressure. We love pressure," Bosh said. "But it's not the kind of pressure you want right now." He paused and added, "We've been through worse." Yet while that is true, considering the Heat stood on the brink of elimination just over a week ago before winning Game 7 of the Eastern Conference finals against the Indiana Pacers, the Heat during the franchise's three years of the Big Three era have never looked as uninspired as they did Tuesday. "You usually get what you deserve in this league," coach Erik Spoelstra said before Wednesday's practice. What the Heat wound up with was the worst loss in both their playoff history and in any game, regular season or postseason, in the team's Big Three era. "We watched film," Bosh said, "and it was worse than a horror film, to be honest with you." At times, it was as if both LeBron James and Dwyane Wade were merely going through the motions, especially on the defensive end. "It's disappointing we didn't play the game defensively the way that we can," Wade said during his podium session Wednesday. "We're not pointing fingers at each other. We're not pointing fingers at anyone. It was collective, as a group. We all had our hand and our part in that.
