1.what does "elegant ritual" mean? Does it mean "accurate sports rules"?
And does "the psychology mixed with physicality of a sport" mean "the psychological elements and body movements"?
(context: But it proved invaluable, for the qualities that make a good cricket commentator—a sense of timing and acute observation, a passion for elegant ritual and the psychology mixed with physicality of a sport that is baffling to outsiders—all contributed to making Sylvester one of the greatest art critics of his time.)
Sportsmen in general and here, cricketeers in particular, do the same thing over and over, in a particular style and with a certain finesse, as a game progresses. If you have ever spent a long spring afternoon watching a cricket match, you would appreciate the ritual movements of the white-suited players--the pitch, the batting, the arc of the ball hit into the field, the return by the fielder, the running of the bases, etc. These form a pleasant ritual, the atmosphere of which is a major factor in the enjoyment of the game by the spectator.
Each sport creates its own rituals: in baseball, it is centered on the pitcher's preparation, wind-up and delivery; in basketball it is the run down the court, the quick pass and the slam dunk. It is these rituals and their execution that fascinates the aficionado.
