I think it comes down to if they wanted Bledsoe, Brogdon, and Giannis as their ball handlers then Delly is now competing against off-ball players. I think they just decided the SGs they have are a better pairing of speed, length, and height than to play Delly. George Hill might play better off the ball and has better speed/length but I think they will end up with the same issues with him. It's just a slight upgrade for the Bucks. I think they got Hill for one reason and that's to have him guard players like Terry Rozier who torched them last playoffs. If Brogdon or Bledsoe can handle the opposing teams PG, Hill will be glued to the bench much like Delly was.
