Just sayin... PG - Bledsoe, SG - Bradley, SF - Green, PF - Sully/Oly, C - Len/Fav is a nice young core to build around.
The other benefit of the trade... basically guarantees you're continuing to skid and adding someone like Wiggins, Randle, Parker, Embiid, etc ... Since none of the guys we'd be taking back would be much of an impact this season.
The third benefit of the trade is that even if you extended Bledsoe to a max deal and gave Bradley is 6-8 mil and signed our rookies, you're still looking at a bit of cap space. Say you gave Bledsoe Rondo money... then say you extended Bradley at 6 mil. Then say you landed the #1 pick (5 mil)... you're still looking at roughly 18 mil in cap space.
