Again, all due respect but you're confused. Joe Johnson is Iggy in this scenario and yes, he and Igudola were comparable players going into restricted free agency.
Also the Suns didn't trade Johnson and two first rounders, they received two first rounders.
Gasol was a salary dump. It makes no sense to dump a player making $3MM a year. The Sixers are only trading Igudola for young players with potential or picks from a bad team. Otherwise they may as well let him walk.
