Again, this is overblown. Durant had Westbrook, but they didn't have anyone else that great. Adams is a good player, but we're not talking about a hall of famer here. The league is bigger, so talent is generally spread thinner unless teams are really smart or get lucky, or players move. We can bash Durant for playing with one other star and still leaving (and let's not forget Harden was traded to save cap space...how much dumber does that look now...), but then we lionize Bird we seem to forget no one would leave his situation: he played with McHale, Johnson, and Parrish, all HoFers, and Tiny Archibald in the early years of the 80s (another HoFer, albeit past his prime). I mean, who would leave that? Bird was playing in the NBA Finals in his second year. Magic his first. These guys didn't "build" teams, they lucked into being drafted into excellent organizations already stacked with talent.
As much as I love Jordan, it's also hard to get a sense of what he would have done if Pippen didn't come along didn't develop. Or, really, Grant, a pick Jordan hated. If he had the flexibility and the Bulls traded away the third best player on his teams for peanuts rather than try to win a title, he might have jumped ship. We don't know.
