I wasn't aware of this. If I wasn't aware, there's probably others here who weren't aware as well.
Technically, Kyrie has a player option on his contract for the 2019-20 season that would pay him 21.3mil. Obviously, he's going to opt out of that and become a free agent.
The deadline for him to opt out of that final year is June 13th. I guess it's standard for players to wait until the last minute just in case they have a catastrophic injury bicycle accident or something... so expect Kyrie to opt out on June 13th.
Once he opts out, the Rose Rule no longer applies and Boston is free to make their Anthony Davis trade offer. Since this is about a week before the draft, that means we can make our offer (Smart + Jaylen + Jayson + #14 + #20, #22 + future Memphis pick) for Davis prior to the draft. That gives the Pelicans an opportunity to use those picks and fill out the rest of their roster around Tatum and Zion.
For some reason, I had been under the impression that we wouldn't be able to trade for Davis until after the draft - which was complicated, because it would mean having to draft players with those picks and then selling the Pelicans on our draftees. But turns out - they can have a full week to figure out what they want to do with the picks.
Granted, Ainge probably doesn't do that unless he gets assurance from Kyrie that such a deal would get him to stick around. But who knows... Ainge might just do it anyways and figure out the rest from there.
