Here's my stab at it.
Hey Kyrie, you know Danny Ainge is a jerk, right? He'll trade you in a heartbeat if it will benefit his team. The market is bigger here in NYC, and you can play in the Garden more often. You won't have to put up with young players that want a larger role--no one chomping at your heels to take over the team. We can offer you the same contract, but the endorsements in NY will be better than in Boston. On top of that, if you come here, another marquee free agent will also surely follow you! This can be your team, really your team, and you won't have to share the spotlight. You can bring Durant with you, right? Or Kawhi? We'll draft who you want to play with... Next season we'll roll out with You, Kawhi, RJ Barrett, Kevin Knox(he's pretty good!) and your choice of Mudiay, Smith Jr, or Frankie Smokes. Oh, you don't want Smith Jr. on the team? Fine! We'll trade him for assets. I'm sure he's worth a first-round pick, right? If you can't get Kawhi, we'll spend $ on Tobias Harris! That's surely enough to compete in the east! We'll be a playoff lock for sure!
Oh Dolan? Don't worry about him. He's got almost nothing to do with the running of the team...
