Bottom line is Paul for Bradley is a rip off, they could do much better than that in another deal for Paul.
In addition to your valid point above, I really don't see this benefiting any of the teams once the prerequisite picks are thrown in to get Paul.
OKC replaces Westbrook with Blake. Maybe they get to keep Blake for an additional year but I doubt he'd be happy moving from LA to OKC and in a situation where that team might even struggle to make the playoffs. They wouldn't have a PG in that offense and it would be tough to acquire one at this point.
LAC loses both of their named stars and that isn't good for business. Given Westbrook's expiring contract and the loss of both Griffin and Paul I'm not sure they'd have the horses to keep him. A backcourt of Westbrook and Bradley is outstanding but that sidelines Reddick and they'd be a hurting team in the front court.
Boston would have to give up 1st round picks to get this done but Paul and IT don't seem like they could play together at the same time. So the Cs don't really acquire their "third star" when one of those guys has to sit on the bench while the other is playing.
I see this trade as a lose-lose-lose scenario for everyone.
