Oubre is one of those perfect trade pieces -- a guy with some value around the league but isn't one of the crucial top 3 pieces to the team. If trading Oubre (or letting his deal expire) can bring us back a player that potentially could be one of those top 3 players on the team, then you do it everytime.
If Sarver weren't the de-facto General Manager (with zero credentials to be so), perhaps.
But look at the past decade. Logic that applies to well run teams . . . does not apply to the Suns.
You don't get rid of, as I said, a spark plug/fan favorite under those circumstances.
Just as the case of a team that has never won a Championship would not consider the moves
that a legitimate contender would to put them over the top.
With Devin double-and triple-teamed and probably still having to cover both Guard positions
(getting closer and closer to wanting out) and Deandre afraid of contact, we're a long way
from thinking like a championship contender.
