There are others, but this one should suffice to let you know what it'd take to get a trade to work and what won't.
Brandon Wright has always been considered a project for the 1st couple of years, so a stint in the D League shouldn't be a surprise. GSW sent POB to the D League last season and there's talk that he might begin the season as a starter. I doubt any GSW fan is concerned.
