Tobias Harris was a ball-stopper Melo-lite type. Was never really fascinated at all with his game and IMO made the Pistons much less watchable, so dumping him was addition-by-subtraction. Stanley Johnson was an exciting prospect his first few months in the NBA; don't expect a renaissance but he has some talent.
Otherwise, I'm just baffled with the trade ideas going out right now. I think the fan perception and actual GM perspectives have never been this far apart, and I think it's because the NBA is in such a wack with the unstoppable Warriors, the still relatively unstoppable Lebron in the East, and several teams just being unable to afford the new salaries being dished out versus just drafting rookies... and the value of the big man basically hitting an all-time low (although there is still clearly value in having a Whiteside, D. Jordan, etc.).
Basically, any player with 3+ years of NBA salary becomes a negative trade asset unless he's drastically underpaid. Which begs the question: why the **** do owners continue agreeing to terms with free agents that they simply can not afford past a 1-2 year window?
Lastly, I'm just gonna emoji in response to any talk of a Jabari/Lavine pairing.

It is absolutely foolish investing max money in a player with ACL history, let alone 2 of them.
