Scouting report: This opens the Heat's six-game preseason schedule, the first of three home exhibitions. ... The six exhibitions are the fewest for the Heat since they played two in 2011 before that lockout-shortened season. ... The game marks the AmericanAirlines debut of first-round pick Bam Adebayo and free-agent acquisition Kelly Olynyk, among others. ... The Heat have gone .500 in each of the past three preseasons. ... This is the first of five exhibitions for the Hawks, who in the offseason traded Dwight Howard and lost Paul Millsap in free agency, adding Marco Belinelli, Miles Plumlee, first-round pick John Collins and former Heat forward Luke Babbitt. ... The teams split last season's four-game series, again to meet four times this season.
