I read Open but not Rafa (not even sure it's been translated yet). Was Rafa too generic?
Also, I'm not sure Roger is the type to spill warts and all, like Agassi.
Andre book was interesting and entertaining. Lot of tennis talked, inside info like personalities of different players, their behaviour etc. Bolletieri academy, childhood drill with crazy father, lot of personal info (hair, drugs...) but it was all written by grown up man.
Rafa book was... boring (to say it nicely). It was like when 10yo gets a homework to talk about his family. Family was like 80% (history of Mallorca, what are the Mallorcans like and why, how is Tony bad but he still love him because he is part of family. Only once he said to Toni he did not like his approach and he was feeling really bad. Lot of talking about his knee. Tennis is like 20%, that was better but still not like Agassi book. Funny part was when he was talking about the shot making, that when he has like 60% chance to hit a winner, he does not go for it and he waits until he has like 90%. No wonder you have to rewind 10 Rafa matches to make one minute highlights...
