MIAMI - Two days into training camp, the Miami Heat are already finding early answers to the question that defined their offseason: whether the league’s most radical offensive system can absorb a two-time MVP without losing what made it work.

The Heat remade their roster this offseason by trading four homegrown players to Milwaukee for Giannis Antetokounmpo and Bobby Portis, then adding Klay Thompson and Tim Hardaway Jr. The moves transformed a team that was the fastest in the league last season - while playing at the sixth-slowest defensive pace - into one built around a player who averaged a 35 percent usage rate in Milwaukee, a figure no current Heat player has approached. Bam Adebayo’s career high is 25.2 percent.

“There are things we did last year that make a lot of sense for Giannis, but also all the guys coming in,” coach Erik Spoelstra said. “But we want them also to feel comfortable. We don’t want to reinvent guys, we just want to add. There will certainly be some principles that we’ll lean on from last year. In many ways it was great that we were able to go through that for a season, we learned a lot last year and we’ll see how it all plays out.”

Antetokounmpo said the system is unlike anything he has run before but that the movement and pace are already making sense to him. “It’s different,” he said. “It’s probably going to take some time for me to get used to it. One thing that I like is that people move without the ball. That allows us to have space to operate, and get to our spots or to be able to create the open look for somebody else. But we just play fast. We were playing pickup the other day and I was the last guy in transition, which is new to me. They were moving. They were going. We’re going to get so many easy looks, get the scoreboard up to 110, 120 each night, which gives you a chance to win, and we’re going to guard.”

The system Spoelstra built last season was statistically extreme: Miami used the fewest on-ball screens in the league, less than half the total of the second-lowest team, and almost never used handoffs. The result was first in drives, first in isolations, and first in points per game - but only 13th in drive efficiency, 13th in isolation efficiency, and 12th in overall offensive efficiency. Guard Pelle Larsson said the addition of Antetokounmpo addresses the ceiling the system hit against elite defenses. “The system was really good and created a lot of opportunities for a lot of different guys, but we kind of did get stuck a few times doing the same thing over and over,” Larsson said. “When the defense figured us out, we couldn’t move past it. Now we have a former MVP on our team that is a whole system in itself. You can kind of go back and forth and tie them together. I feel like it’s a missing piece to that system.”

Thompson, whose shooting alongside Hardaway Jr. gives Antetokounmpo the movement shooters he needs flaring off high screens, said the transition feels natural. “I think it will be seamless,” Thompson said. “I love the fact that we play fast. I love the fact that the ball is advanced quickly and we’re trying to seek out the best shot. Guys are willing to make the extra pass, guys are willing to cut even if they don’t get the ball just to draw the defender, that’s the type of basketball I’m used to. Just selfless. I think the HEAT exemplify that more than any team.”

Antetokounmpo said his confidence in Spoelstra’s ability to adapt removes any anxiety about the learning curve. “Having a coach like that, you don’t worry about nothing,” he said. “You worry about your job, he’s going to have your back and our offense and defense looking sharp.”

Spoelstra acknowledged an adjustment period is likely but said the transition is less dramatic than it may appear from the outside. “I’m sure there will be,” he said of Antetokounmpo finding a learning curve, “but it’s not that different when he’s been in attack mode. It doesn’t change what he does, it’s what other guys are doing. There are some small things when he’s off the ball that we’ll fine tune and get him moving the way we move, but I don’t think it’s as dramatic as people imagine.”

The Heat open the regular season with the full roster expected available, giving Spoelstra and Antetokounmpo their first competitive test of how the system translates from training camp to game action.
