Sure, it would have been great if Paul George had signed with LA, but Maglinka blew that one by refusing to trade for him when he was theirs for the taking. Trevor Ariza took a huge one year deal with Phoenix. What other all-star shooters were out there for the taking? I sincerely doubt that James was begging the Lakers to sign a player that he's had personal problems with over the years (Stephenson) or the well known bonehead That's So JaVale McGee.Maybe they could have found some vets who could shoot. In hindsight, they would probably have been better off with G league players than head cases like Beasley and Stephenson.
I get that this was going to be a transition year, but any GM who willingly puts Beasley, Stevenson, and Rondo on the same team is looking for problems. They shouldn't have been an option, even if they had reps as stable team oriented players, just for the lack of three point shooting.
This might come as a shock to you, but Maglinka is a legitimately bad GM as shown by their pre-LeBron track record. There's nothing in there recent moves that's any break from the mediocrity.
