Meanwhile, two teams heavy with homegrown talent just played in the finals for the title.
I am taking great pleasure in watching these "glitter" teams, who acquire all-star talent in free agency by falling out of bed in the morning, end up painting themselves into salary cap and draft pick corners with no good way out because the mega-stars that they signed become unhappy when things don't go exactly their way and then look for the easiest way out of town.
not that many teams are actually built through free agency. The Nets obviously acquired Durant and Irving that way, but most of the rest of the roster was trades. The Lakers signed Lebron in free agency, but the rest of the main roster was trades or drafted players, and trades of almost exclusively homegrown talent to acquire said players. The Heat did acquire Butler and Lowry in free agency, but the rest of the key players were draft picks (or players they signed very young and developed).
The last team to win a title where at least 2 of the 3 best players were acquired in free agency were the Heat in 12 and 13 (the Lakers in 20 were arguable depending on who you consider the 3rd player i.e. KCP, Green, Kuzma). And frankly, those might be the only 2 teams in history that fit that description.
