Someone still bitter about losing to an injured Murray at IW in 07 I see
100% correct, it all goes back to Indian Wells in 2007... Tommy Haas also said in his post-match interview that he was waiting 5 years to finally bash Murray, since that was his most painful loss in the last 5 years
If you define gamesmanship as "disrupting the natural flow of the match to try to gain advantage" then there are many, many players out there with many different tricks that are gamesmanship, most of which are not actually breaking any rules, so you have to deal with them and not hide behind this as an excuse when you then lose to them.
That is playing down bad sportsmanship and nothing else. I hope you saw that match against Gasquet at the French as a fan of this sport, not just through Andy Murray signature glasses. cheers
