In rock 'n' roll, hitting rock bottom is straight forward. Booze, drugs and reckless behavior of all manner conspire to send the ailing star to the brink. Paint-by-numbers self-destruction, it was immortalized to hilarious effect by John C. Reilly in "Walk Hard: The Dewey Cox Story." Killing yourself was never more fun than when Cox shouted between swigs of alcohol with a groupie, "This is a dark @#$##@ time."
The equivalent descent into darkness in football is being written right now, but poor old Arsenal can't even have a few moments of guilty joy on the way down.
