As Carol said, above, you do choose when you believe a player has injuries, and when you don't. Nadal's knee strapping in 2008-09 meant nothing to you and a lot of Fed fans when he lost at RG, even though the knee problems were known, and also sometimes apparent. That's selective believing of a player, on your part. The fact that you can say the bolded above, and not notice the irony vis-a-vis Nadal's chronic knee tendonitis and your attitude towards his other injuries makes me have to laugh behind my hand. Also, there's nothing "famous" about Nadal skipping the AO for lack of proper preparation, after a 7-month lay-off...only that you yourself keep hammering it. And pretty much you, alone.
Carol can be very protective of Nadal, and go on a rant about it. But she's not wrong about your double-standard, on this point.
