"These are not major adjustment trades we made," Spoelstra said. "We're familiar with both guys."
Spoelstra said he learned of the trade possibilities from Heat President Pat Riley just prior to Thursday's practice.
"I went up to Pat's office right before practice, maybe 45 minutes just for a quick update and he said there's a possibility that something might happen with Luke and something might happen with Dwyane," Spoelstra said. "I was about to walk out the door and stopped and said, 'What? Dwyane who?' "
Wade said it was as much of a whirlwind on his end.
"About 11:45 I left my house, heading into the practice gym in Cleveland," he said. "And about 12 o'clock I got a text from my agent Leon Rose. I haven't gotten a lot of '911 call me now' messages on trade-deadline day in my career."
That's when he found out he was returning to the organization after 11/2 seasons away.
"Winning three championships, what this organization has been and means to my life, you do get out and see it's different," he said. "I'm definitely excited to be back. The jersey and colors fit."
Both Wade and Babbitt were with the team for Friday morning's shootaround.
"It absolutely felt like perfect timing for both parties," Spoelstra said. "It was surreal how it came about."
Of Wade's acclimation to his once-and-again teammates, Spoelstra said, "Looking forward to seeing Dwyane's reaction to see how much they've grown. They're a lot different from the last time he was here. How their confidence has grown. That will probably be fun for him to experience as well."
As for Wade playing as a closer, Spoelstra said, "He could. That's another area of his incredible greatness. But we're not asking him to come here and bail us out. What he absolutely does is help everybody."
Of Wade's conditioning, Spoelstra said, "Come on this guy has been playing an NBA season. I mean you know how we are. But this guy has been playing an important active role all season."
Wade smiled about the talk of Heat conditioning and culture flooding back in the moment.
"I had a different zip code and different jersey on my body," he said of his time with the Chicago Bulls and Cleveland Cavaliers these past two seasons, "but my mind was always here."
