I could see Exum and Rondo as a version of Johnson/Nixon or Kidd/Kevin Johnson.
Yeah, I'd be happy with the two PG thing. Thing is with Rondo and Exum is that they're both real PG's, with different focuses and skillsets. Obviously rondo being more facilitating and Exum leaning towards scoring. I don't think they're too bad a compliment for one another. Shooting may be an issue, but we have some decent floor spacers.
Alas, unless we get the 3rd pick and pass on Embiid, we're not likely to be able to get Exum unless he forces his way here via his agent. Not impossible if Orlando gets a top-2 pick, but I expect them and Utah should really covet Exum.
