I'm just not seeing the stars that you see.
Labron is a star for sure, he controls the game and can dominate when he chooses, every night, so let jump past him.
Love had great stats when he went to Cleveland, and if he and LBJ had a ball apiece he would most likely have a huge impact, but we don't play with 2 balls in the NBA, we share one. His numbers in Cleveland were good but not eye popping, throw in his defense ability and "yada yada yada"
Some of the player you name are good talented ball players, Monroe, Butler, Bosh, Wall, Beal, but not dominating stars in the caliber of Labron. They're very controllable, some nights great, some regular.
Some stars you mentioned are past their prime or continually injured, Wade, Rose, are past their prime, with "big names", but are mostly a shell of their prime years. I wouldn't want either to build around.
Giannis, has a great nick name, and potential, but you can't call him a star. Parker, was having a nice rookie year until he blew his knee out, the jury is still out there.
My point is, there is a difference between a real LBJ type star, and a good solid pro with a recognized name, mostly because he was once a free agent.
