No, I wouldn't trade Rondo for Bledsoe.
Bledsoe still has a few big question marks next to his name. He has never ran his own team. Having Dragic there alongside him in Phoenix last year was a big help to his game. Bledsoe struggled the year before when asked to start in CP3's absence. So, I would want to see Bledsoe run the point / lead a team by himself before I consider giving up someone as valuable as Rondo in a trade for him.
