Samprass, Agassi & to some extent Federrer all played risk free controlled game.They played only to win managing just do that.But not so great enertainers like Becker,Ivanisevic, Edberg.Though records don’t speak much for Ivanisevich but the entertainment vaule he provided was of high quality in bits which he could'nt compile and convert them to winning performaces and ended loosing to potentially lesser players like Aggasi & Samprass.
