Is Novak Djokovic the Eric Liddell of our times?

Liddell was the Scottish sprinter who famously refused to run in the 100m event he was favoured to win at the 1924 Paris Olympics because the heats were scheduled on a Sunday.

Liddell, a Christian who insisted Sunday was a day of worship, was labelled selfish as a bad sport, a coward, and a traitor for putting his principles before the pursuit of sporting glory.
