I wouldn't trade back Levine for Fox straight up at this point.
That's why I rated the job Monte did before the trade line as A+. With the measly Bulls Zach alone won many impressive games. On the road against Bucks, Celtics and couple other elite teams. Zach now has a green light from the coach to do whatever he wants to do and it shows results. Scoring? Sure. He was and is a willing passer. Zach will result in some turnovers. Especially it was an "issue' with the Bulls, but just because talent around him was on such lower level compared to what he has around him in Kings. I said previously that Zach actively looks to feed bigs in the paint. Not only that. When Zach drives and attacks - defense have to "honor" it and try to do something. Guys in the paint are available, but paint is already packed. Option B - hit shooters on the perimeter. He does that and Lyles, Monk, Keegan, Ellis have an open shot.
First 4 games Zach played with Kings were mehh, atypical for him, but what we should expect? JV adjusted to the new team easily (JV is big, long, strong with soft hands - everything a C should be). Last 4 games Zach played like he played all his games with the Bulls. Nothing extraordinary to be fair. Still, foolish turnovers, but it will go down.
I'll repeat myself - JV as a back-up C is a luxury. JV started ~800 games for the teams with the winning record. Game against Jazz was what JV is. When JV started in the league, refs usually would reward him with fouls on even slightest occasion. Thus the pressure not to get the team as a whole into early foul troubles. Now JV doesn't care if he fouls out in 10+ minutes.
LaRavia is a peach. Offense will come, but when Jake is on the floor - he is always around the hottest place on the D and it ends up with positive outcome.
Zach attack. Explosive, picks up speed like a rocket.
JV - I said everything. ~90% on FTs, can hit long ball with the smile too. Better defensive and offensive rebounder than Domas, just can't play the same minutes as Domas does.
Jake - rave on D. Very high bbiq.
Fultz - started for Orlando last season in play-offs. Exceptional bbiq. True PG.
BTW, against Hornets and Jazz we saw a happy, smiling, relaxed Kings team. Not only players who were in the game, but other guys around them. Assistant coaches, other personnel.
