Spoiler Alert: Disclosure Day isn't really about aliens or anything like that. It's about magical glow sticks that are never explained or exposited, but comprise the overwhelming bulk of the plot. They also do whatever Spielberg and Koepp need them to do whenever the plot runs aground.
Maybe SGA is unethical.
Maybe SGA is destroying the game.
Maybe SGA is only a free throw merchant.

Nobody complained when Kobe had 3 seasons with more free throw attempts than SGA this year.
Nobody complained when MJ had 4 seasons with more free throw attempts than SGA this year.
Nobody complained when Bron had 4 seasons with more free throw attempts than SGA this year.
Maybe SGA is just unguardable.
