Carl and I use the fitness sagas of Novak Djokovic and Rafael Nadal as a springboard to talk about injury management--the way in which players handle constant nagging injuries, whether that means adapting their tactics, changing their pace, rearranging their schedule, or just plain suffering. We also wonder how much undisclosed injury and fatigue affects match results, or if commentators focus too much on questions of physical readiness at the expense of talking about the tennis itself.
