Ainge doesn't have an emotional attachment and the ownership allows him to have final say. Cuban has an emotional attachment and he has final say. According to reports he's the one that pushed for the Rodman signing and the Rondo and Odom trades.
I'm picturing the scene as it looked around the Rondo trade table:
It's a Friday night and Danny Ainge approaches a bunch of potential trade partners with his offer"Hello. My name is Danny Ainge and my product is Rajon Rondo. Rajon Rondo is an all-star point guard who will solve all of your floor distribution problems. I'm asking for a couple of first round draft picks and a few throwaway players in exchange for this athlete.
Imagine this: You have a great defense. You have players who can score. But nobody can get them the ball! Now, that problem is solved with the new Rajon Rondo point guard. He consistently leads the league in assists and is often willing to pass up an easy lay-up just for the opportunity to kick that ball out to the corner and get another assist. He rebounds, plays Connect 4 and occasionally tries on defense. Now, who's going to be the first to get the all-new Rondo."
Cuban: What's Rondo's history?
DA: Rondo is a world champion, having led the Celtics to the title in 2008.
Cuban: 2008? That's a long time ago. What has happened since? It sounds like he has gone downhill.
DA: It's not him, it's the team around him. His teammates aged and we haven't picked up any superstars. Then, we traded two of the Big 3 to Brooklyn for their entire future.
Billy King: It's true.
Sam Hinkie: I heard that he got injured. But I'm always willing to make a deal. Give me Rondo, the three picks from Brooklyn and your 2017 first-rounder and I'll give you a protected 2nd rounder in 2027.
DA: Sam, thank you so much for the offer. I have to pass, though. My partners would never go for it.
SH: Okay, we'll make the 2017 pick a second rounder.
DA: No deal.
Billy King: Look, you guys already took advantage of me once, and after last season, I'm afraid to go out in public. In fact, anyone with whom I've ever traded has taken advantage of me. I like the idea of using your Rondo with Garnett, but I just have no experience in the field of winning. I'm out.
Mitch Kupchak: You dodged the injury question. Didn't Rondo get injured a couple of years ago?
DA: He did tear his ACL a few years ago, but he's been perfectly fine since. Well, except when he "slipped in the shower" and broke his hand. On the plus side, he didn't get a concussion from banging his head on the door.
MK: I'd love to have the guy, since Kobe needs somebody to talk with on the bench, but I just don't have any cap space. I'm out.
SH: Let me throw another proposal at you...
Ryan McDonough: Uh oh, here it comes...
SH: Be quiet Ryan. Look, there's a reason I'm called Mr. Draftpick. I've got a bunch of them. So here's what I'm going to do. I'll give you a 2034 first-rounder for nothing. In exchange, however, I get 10% of all the points that Rondo scores until we make the playoffs. After that, I'll drop it down to 5%.
DA: Um, Sam, I don't think we can do that.
SH: Then you're dead to me. I'm out.
Voiceover:
Two individuals remain. Ryan McDonough once worked for Ainge and knows how he thinks. Mark Cuban, though, is looking to make a big splash.MC: Okay, I'm interested. I don't know if you have a real business here, but I'm in it to win it and I like to see my name in the paper. Besides, I have so much money that I can simply buy the NBA if I don't like the way it turns out. Here's what I'll do: I'll give you a potential first with weak protection, along with Brandan Wright and Jameer Nelson, in exchange for the remaining 40% of Rondo's potential.
SH: Whoa, Cuban comes out swinging! Ainge, you're crazy not to take the deal.
BK: It's true. He's only giving you one draft pick in exchange for a potential disappointment, while I gave you three, so it's not as good a deal. But it's better than anyone else will offer you.
RM: Look, I just can't top that one. I'm out.
MC: So I'm the only one left. I'm setting the 24-second clock.
DA: Can I have a minute to talk to my partners?
MC: 24 seconds. Starting now!
DA steps into the hall. We can hear him talking into the phone, "Look, it sounds like a pretty good deal. Uh-huh, yeah, I know that's how Costner did it in that movie. But that's the same guy who chose to be in Waterworld. I'm not using his methods. Okay, thanks, goodbye." DA re-enters the room.MC: So what's it going to be Danny, Yes...or...no?
DA: I need one more player. Throw in another first-rounder.
BK: You're crazy. Cuban, don't do it. That's how he screwed me.
MC: I can't do it. But I'll throw in Jae Crowder. He'll try lots of 3-pointers and you can nickname him "Clam." And you have to throw in Dwight Powell.
DA: Mark, I also want season tickets to the Mavs games. You have a deal!
Applause is heard and the GMs all congratulate DA as the closing credits roll.RM: Mark, you're crazy.
MC: No way. I'm feeling good about this one. An all-star guard for a draft pick that will never be a lottery pick since we are going to be so good for the next decade? I hosed that guy.
MK: Sure, Mark. Hey, give me a call if you want to talk about Kobe...
