In the NBA, as in other facets of life, size matters.
Nobody wants size to matter. It poses an unfair advantage to the party who’s been endowed with it. Regardless, it exists, and whoever has it will use it.
Market size, that is. Get your mind out of the gutter.
In free agency, the teams that play in the league’s biggest markets always get first dibs. Look at the Los Angeles Lakers. They don’t even need to properly manage their roster - in time, a LeBron James will decide that donning the purple-and-gold is suitable for his brand.
