Video: Defense begets offense, giant LeBron James alley-oopsDan DevineBall Don't LieApril 19, 2011The Miami Heat got a lot of attention during the regular season for their high-octane offense and all-too-frequent flash, but that running and gunning was fueled by a tenacious defense. Erik Spoelstra's squad posted the league's fifth-best defensive efficiency this season, allowing just a shade over one point per possession and finishing ninth in the league in team blocked shots, which often facilitate easy transition opportunities.That's exactly what happened during what was, frankly, a difficult-to-watch first half of Game 2 between the second-seeded Heat and the seventh-seeded Philadelphia 76ers in Miami on Tuesday night. Miami held Doug Collins' team to just 31 first-half points; halfway through the third quarter, Philadelphia's effective field goal percentage was still below 30 percent, which you might categorize as a complete and utter offensive apocalypse.During the particularly memorable second-quarter sequence above, Heat center Joel Anthony stymied consecutive attempts by Sixers forward Thaddeus Young, sending the second off the backboard. The ever-opportunistic Dwyane Wade grabbed the carom and immediately turned up-court, taking the middle of the floor and slinging a pass ahead to point guard Mario Chalmers, who had leaked out in transition.The sole Philadelphia defender in the area, Andre Iguodala, took a step toward Chalmers, leaving the lane wide open for LeBron James, streaking down the right side of the court. All Chalmers had to do was get it near him. Tic-tac-toe.Too easy, drill sergeant, too easy. And, if both teams' present form holds, 2-0 Heatles. UPDATE: Both teams' forms held.Original video via Ben Golliver.
