Way better? That's ridiculous. On paper, it's essentially a wash. Parsons is much younger and cheaper. Parsons will only improve; Iggy will likely decline over the course of his next contract.
That could be very interesting. So Harden to point guard, and you have Beverly as the back up if you need to give Harden a break. I could see this happening, or working if it did happen. Maybe Iggy is waiting to see if Howard signs?
Actually, I just realized you have two possible lineup combos here: PB JH AI CP DH or else this: JH AI CP ?? DH Those are some very powerful lineups. I'm not sure if Iggy will sign for what Houston could offer him if they deal Asik or Lin (or both), but I could see Houston trying to do the deal. Those lineups could be monsters.
