"Bird knows we've given him very good endorsements," Karl said.
Spoelstra did not address Andersen's off-court questions specifically, though insisted that Miami has no qualms about bringing him into the mix.
"We've done enough research on him. We feel he fits in very well," Spoelstra said.
And yes, Heat president Pat Riley's preference for players to not wear headbands — a policy that has been relaxed a bit in recent years — will not apply to Andersen.
He asked for permission, and apparently got it in a mildly comical manner.
"I was told about the code of conduct around here," Andersen said. "I went into Pat Riley's office and I asked him if it was cool if I could wear my headband, because I do a sweat a lot. And he was like, yeah, because he didn't want me perspiring on his nice floor."
No, what Riley wants is for him to rebound on his nice floor.
Rebounding has been a major question for the Heat in recent weeks, even while the team has held on to the top spot in the Eastern Conference race. So the team made roughly 21 feet worth of moves on Sunday, signing both Andersen and Jarvis Varnado to 10-day deals — it's Varnado's second such contract with Miami — and recalling another big man, Dexter Pittman from the NBA Development League team in Sioux Falls.
Miami entered Sunday ranked 29th in the 30-team NBA in rebounds per game.
"I'm here to help assist in any kind of rebounding or defense that I can provide to an already outstanding team who are defending champions," Andersen said. "And I'm just ecstatic to be here and I'm ready to get back to blockin' and rollin'."
Andersen said he had his left knee scoped in August, but has been able to work out in Texas and Colorado while waiting for an NBA team to call. He didn't reveal how good the knee feels now, though pointed to his tattoos as evidence that he's got at least some level of pain tolerance.
"That ain't gonna keep the Birdman from flyin' and getting in there and getting some rebounds and bangin' and playin' hard," Andersen said. "As you can see, I'm pretty much accustomed to pain. But it ain't gonna stop me from coming out here and assisting these champions and trying to help them win another championship."
