Certainly there have been worse transactions in the history of sports. Take your pick:
The Red Sox selling Babe Ruth so they could finance a Broadway musical. The Baltimore Colts forcibly dumping pouty Sanford rookie QB John Elway for Mark Hermann and a couple of offensive linemen. The Dodgers trading promising Pedro Martinez for second baseman Delino DeShields.
But somewhere down the line, in the zip-zip world of stock car racing, comes this one:
Dale Earnhardt Jr. for Kyle Busch.
It really wasn't a trade, per se, but it was definitely a choice for Rick Hendrick in 2007.
