You're forgetting one thing: It didn't have to be either or. A salary dump and downgrade at the PG spot was a choice that didn't have to be made at the deadline. The season was over at that point, and we didn't have Gordon. It was a choice that backfired. An unprotected lottery pick and the better PG for 5 million in cap saved a year?
And saying that we have the 1-3 draft pick next season considering what happened yesterday is far from the truth. I would have waited till after the lottery to see what we had and made a move to send Baron out then.
The most important thing to remember is that the move we made wasn't a dire need. it was a salary dump that could have been done in the off-season.
