Phoenix chose Oubre over handing anything to the Lakers, if you've been keeping up.
The Suns aren't on the Lake/LeBJ timeframe.
I think they just preferred Oubre to KCP.
Uber is aggressive, KCP more in the Courtly mold.
Both would need to be re-signed.
If I were PHX, I'd try to move Ariza for someone under contract and/or a pick. Also I don't see the rush. Saturday is the first day Ariza (and many others) could be traded. I'm sure they've been listening to offers for a couple weeks. But what's the need to make the first deal?
I assume they just liked Uber-K.
And/or their Rent-Ariza offers weren't that great (not so easy to match $15M when Suns want yute -- which is where AwfulRivers ending $12M came in).
In any case, a core of Booker-Oubre-Bridges-Ayton is super young but needs a PG badly.
