While I still think this is stupid, I do like some of the potential drama this could start.
Look at last year for example, LeBron and Curry would be captains. What if Curry doesn't take Durant with his 1st pick? What if LeBron doesn't pick Irving at all and so Irving ends up as the last pick among the starters and gets put on Curry's team by default?
Same thing when you get to the reserves, how does it look if Curry doesn't take Thompson and Green with his first 2 reserve picks? LeBron takes Draymond with his 3rd reserve pick and starts whispering in his ear, "look how Steph doesn't even respect you."
Think of the potential drama during the Shaq/Kobe years when one of them is captain but doesn't pick the other.
Still stupid, but there is that added "drama" element I like.
