What's interesting to me is that they're three different players. Blake is the solid guy who isn't going to hurt you with mistakes but who isn't going to with the game for you. Bayless is more of a combo guard who can break down defenses with his ability to penetrate. Sergio is the high-beta pure PG. If we get Livingston, that adds a fourth type--the huge, defensive oriented, pass first PG.
The funny thing thing in that article is how mediocre all the players mentioned throughout it are (aside from Artest and maybe Battier). The real story here is whether Roy is moved to PG by midseason so that Rudy can start. In my mind, Blake is already out of the long-term picture and it's a competition between Rudy and Bayless for the other starting guard job by midseason. Rudy seems more seasoned and is a better perimeter complement to Roy, but Bayless is better equipped to guard point guards. (I don't see Rodriguez or Livingstong doing anything but battling for 3rd/4th string point guard this year. Given how the minutes project, that's probably not a very important job.)
