Aside from the guys are hired by the individual teams (those guys are supposed to get nutty), sportscasters are supposed to be fair-minded, even tempered individuals who paint a picture of a sporting event for all fans watching or listening, no matter which team the viewer or listener is a fan of. The guys on this video must have fallen asleep in sports broadcasting school, as they have all lost their cool, and possibly their minds, and even more possibly, their jobs.
Enjoy this video of sportscasters loosing their cool.
