Parker posted a .587 TS% with us, 20-9-3 per36. He was really good. Also had a very positive net rating in March. Finished with a positive VORP and DBPM. ...
No, alas, he wasn't "really good," though he did some good things. His 58.7% TS% was, as you say, well above average. Unfortunately, that doesn't tell us much about his offensive efficiency until you factor in the extra 1.75 turnovers (i.e. beyond an average 4) which he also committed per 40 minutes. Assume he's average on turnovers & move those extra ones over as extra missed FGAs, & his TS% falls to .511 -- way below average.
Overall, on the rest of the box score stats he was just slightly above average. Then there is Jabari's defense....
Nonetheless, yes, he was better with us than Bobby Portis.

That's stretching it, I'd say. In terms of value. But, guys picked as high as Jabari usually get overpaid right up to the day no one pays them at all, so I would speculate that some team will give him more per year  -- & on a 2-year deal. 
A team with an extremely strong culture -- the Warriors, say -- might do that, & that might be a good place for him to go, as well.
