i'm well versed in the art of gamesmanship, and have seen some of conners' lesser moments (screaming abuse etc).

nearly all sportsmen in every field of are guilty of some degree of gamesmanship, be it djokovic calling for the trainer all the time, nadal's redressing each point, sharapova's grunting ().
i just feel there's levels i don't personally like to see crossed (eg conners abuse, fielders in cricket appealing catches they know they haven't taken). I can appreciate why people do them, and can appreciate their success however don't expect me to like the person for it..
