Sporting events running past its allotted time, especially when the time period proceeds into the news, is nothing new and nothing's gonna change that unless the networks decide they're no longer want to be in the sportscasting business.
I know certain people are set in their ways as far as a particular stations they watch for news...I get it, locally there are certain stations I avoid (well, namely one, KTTV--a victim of Fox's bastardization of their local newsrooms), but I'm not getting bent out of shape if a sporting event runs past the allotted time. If I want to watch the news that badly, I'll find another station.
