​MIAMI, July 16 (UPI) — Miami Heat president Pat Riley said Thursday that acquiring Giannis Antetokounmpo and Bobby Portis to form a power rotation is a “dream come true.”Riley made the comments during the introductory news conferences for Antetokounmpo and Portis, who were acquired earlier this month in a trade from the Milwaukee Bucks. The Heat gave up a haul in the swap, including sharpshooter Tyler Herro and several young assets and draft picks.AdvertisementAdvertisementAdvertisementThey now appear set to deploy a gigantic, physical lineup, with an emphasis on defense, anchored by the 6-foot-11 Antetokounmpo and 6-foot-9 Bam Adebayo.”It’s sort of a dream or an aspiration of mine that came true,” Riley said at the Kaseya Center. “I think with Bam and Giannis and Nicola Jovic and Bobby, we’ve got a very potent, power rotation that is very versatile.”Riley cited anxiety during the process of luring Antetokounmpo to Miami, which he said nearly occurred in February. Antetokounmpo called the process “tiring” and told Riley he was “scared” during a phone call prior to his arrival. But he also said he is excited to compete for a new franchise and wants to be “coached hard” by the Heat’s Erik Spoelstra.AdvertisementAdvertisementAdvertisementThe Heat, who have typically leaned on their defense for success, went 43-39 last season, failing to make the playoffs for the first time since 2018. They posted a franchise-record 116.7 offensive rating, but also logged a franchise-worst 114.5 defensive rating.Spoelstra said he expects Antetokounmpo and Adebayo, who attended Thursday’s news conferences, to fuel new version of the Heat defense.”The biggest thing with the both of them is they’re elite competitors,” Spoelstra said. “It matters to them to defend. They are gnarly competitors. And if we’re not defending the way we want to, I’m sure they’re going to let everybody know.”That’s how you build a great defense.”AdvertisementAdvertisementAdvertisementRiley said the assets the Heat surrendered in the trade were “great, young players,” but placed an emphasis on winning “now.” Antetokounmpo, who won a title with the Bucks in 2020-21, mulled his choices before ultimately landing in Miami. He said he thought the move was his best route to another title expects the Heat to be successful immediately.”We are going to be good,” Antetokounmpo said. “We are going to be good. I will speak things into existence. It’s going to happen.”Antetokounmpo and Adebayo are expected to be joined by guards Davion Mitchell and Tim Hardaway Jr. and forward Andrew Wiggins in the Heat’s starting lineup, with Portis likely coming off the bench.Portis, a frequent Sixth Man of the Year candidate, said he would again relish that role in Miami.”In the league, you have to find a niche, find a role that you can help stay around and help impact winning,” Portis said. “In my career my career trajectory I look at what I can do and where I can fit at. For me, it’s been coming off the bench and being
