What I know about NASCAR would fit on the head of a pin.  Hell, it would fit on a surface smaller than the head of a pin.  I see cars on television racing around a track and the first thing I wonder: how can anyone sit and watch that for four hours?

What I've resisted, however, is the urge to put NASCAR down.  To each his or her own.  But even with my miniscule knowledge of this particular motorsport, I know bad business when I hear and read about it.

Today meet Teresa Earnhardt, window to Dale Earnhardt Sr. and winner of Bad Business Person of the Year.  After today, no other nominees are necessary.  For those we don't bask in the glow of NASCAR news daily.  Mrs. Earnhardt allowed her stepson, Dale Jr. to get away from his late father's racing team.

I could probably write a nice long narrative about how you should never allow ego and money to get in the way of family, but I wouldn't be able to do it any better than Yahoo Sports' Dan Wetzel does here.

In short:  DEI had the most popular driver in the sport and the perceived heir to Dale Earnhardt Sr.'s legacy and they allowed him to speed off to find riches elsewhere.  The big difference - he'll be taking tons of revenue with him.
