I say, 5%. I don't know about all of you, but I'm sick of all these possums on tour. "Waaaah, I just fell and it HURRRTS. Mommy, I have a booboo." "Waaaah, I just rolled my ankle! OW!!!" And then they limp around the court against one of the very best players on the entire planet, and continue to compete, winning games, sets, and even matches. It's just so lame, and makes tennis players look like real p******. I believe Murray may have been in pain in this one, but he's cried wolf so much that I can't help but roll my eyes again. I would estimate 95% of all tennis "injuries" aren't even injuries at all. They're players who need a band-aid and are milking it for all it's worth. These guys act like they're in some video game and are losing "power" every time something happens. "Uh oh, energy level down to 76%. NOOOOoooo! Need to find a power up, fast!"
