The race at Phoenix is just another chapter in what has seemed to be a disasterous year to be a crew member for some teams. Dale Earnhardt Jr.'s crew is a firm example.
Every race has seen Jr.'s chances of winning a race quickly evaporated by a pit miscue. Everything from loose lugnuts to a shortened pit sign have transpired. Loose lugnuts clearly being the problem, Jr. has seen many mistakes by his team that would personally have slayed me after the third straight race.
The problem doesn't come with Jr.'s crew as much as it does by the new rule mandating that the fifth lugnut must be placed farther against the wheel than the other four. Why NASCAR made this rule change I don't know but it will require Jr.'s crew hitting the practice wheel a couple more times than usual if they want to make a run at the championship.
It's never to late to correct mistakes, for example, take Mark Martin winning at Phoenix.
