One disconnect I don't understand: none of the other 29 teams wanted him at a very modest price, but he's going to get a $180 - $200 million max contract?
Why? If no teams are interested, it sounds like he'll be lucky to get half that, or even less.
I don't think that necessarily follows. He very well may sign for $180 million somewhere when all is said and done. But some players sign for the max and are worth that to only a few teams. Some sign for the max and are worth far more than the max to every team in the league.
What this one event tells us is that (assets surrendered in trade) + $180 million contract > Boogie's value, for most teams, under the assumption he resigns. The assets that the highest bidder gave up weren't worth that much, but he could still be worth the max to many teams.
So, if he's worth just more than the max but not a lot more, many teams would pursue him in free agency but not trade for him now.
And of course even if you think he's worth it, there's the prospect that you don't retain him. The expected value of acquiring him would include that too (probability he's a rental times his value, for 1.5 years, minus the value of the assets traded).
