The numbers are a little silly, really.
To wit, the deciding game of the NBA Finals this year drew 12.4 million viewers. Last year's World Series averaged over 11 million viewers. NHL Stanley Cup? Try about 4.8 million viewers.
And how about last year's NFL Hall of Fame Game, quite possibly the least important, least interesting, lowest stakes game on the entirety of the NFL schedule? Yeah, that did 7.3 million viewers.
