Guys, I have a bit of a curveball theory here.
If you remeber not too long ago, a report came out saying that one team in the top 3 had given Josh Jackson a promise that they'd draft him if he fell to them.
Now let's say that rumor was true...we already know this team wasn't Boston, since Jackson never met with the Celtics. That means it must be either Philly or the Lakers who have this promise.
The Lakers just gave Jackson a second workout and word is that it didn't go well AT ALL. Now, if the Lakers already promised Jackson that they'd take him at #2, why bother even having a second workout? It doesn't fit, so i dont imagine it's the Lakers.
That leaves Philly as the only team who could have likely made that promise, right? Now suddenly, after the world starts taking about Boston's interest in Jackson, Philly agrees to give up draft picks to move up in the draft? Could it be that they are moving up, not to take Fultz, but to honour their promise to Jackson?
Could it be that Boston liked Fultz, Tatum and Jackson equally, with Jackson just slightly ahead, but happy to go wider way?
They tell Philly that they are leaving towards taking Jackson, Philly folds under the pressure, gives in and trades up.
Now worst case Lakers take Fultz (very possible), in which case Boston takes Tatum.
Or best case, Lakers select Ball and Boston takes Fultz.
IF Boston knows for sure that Philly is taking Jackson, then that's basically a win-win for Boston. They pick up an extra pick or two AND still get one of the two guys they wanted regardless, and saves a couple of million on the rookie contract...which helps them to after a max free agent.
If the rumours about Jackson getting a top 3 promise are true, then this makes a lot of sense.
We all immediately assume that Philly is trading up to take Fultz, since so many people have him as the consensus #1 pick. But if Philly love Jackson and really did make a draft promise to him, and if everybody is convinced that the Lakers will draft Ball, then it would make total sense for Philly and Boston to make this trade - Philly gets Jackson, Lakers get Ball, Boston gets Fultz - everything works out as planned, everybody gets the guy they want, and Boston gets an extra pick or two out of it as assurance that evening works to plan.
