I'd love to get Lillard, but he's the guy the are building around now.
As far as our point guards... the time to get a one year rental has passed for now. We will roll with our current guys which I am fine with. Trey is streaky, but if he stops shooting on his off nights he won't lose us games and on the nights he is hot (although they may be few) we almost always win. Neto will change a few games with his defense and passing, but won't kill us either. If these guys aren't working out there may be teams that once they realize the playoffs aren't happening will sell off guys for cheap around the trade deadline. Possible guys we could get would be Darren Collison, Avery Bradley, George Hill, Kemba Walker (not my favorite personally), Jeremy Lin... there are probably others.
Some bigger names could become available if teams decided to blow it up Jrue Holiday, Kyle Lowry, Ricky Rubio (not a fan personally). If something really weird happens Bledsoe and Teague might become available if we went big.
Right now we just have to wait and see though.
