Personal? This is a debate with differing opinions, nothing more friend.
With Gallinari's contract off the books they get relief they would be looking for in a Paul deal. If they bring him back then they have the same roster that made the playoffs. Why should PHX aid in their rebuild giving up 2 starters and a draft pick most likely? PHX has the leverage here as OKC apparently needs to move Paul, so why should PHX give up so much?
They don't have to sign a big time FA this year, they can either save the space for next year or trade Paul to a contender, PHX isn't the only trade option for them. If we add a FA like Ibaka to solidify the PF spot and draft picks like Haliburton and say Jalen Smith and they make an impact as rookies then I think we could make the playoffs. I don't see Chris Paul as an upgrade over Rubio/Oubre/#10/Ibaka/cap space.
In a draft like this were level of talent is so close to each other in terms of grade then chances are your need will match BPA. Haliburton is easily a Top 10 guy, Tyrell Terry's stock is on rise. Any number of players could be justified being taken at #10 that could fill a need for PHX.
