Yeah, but when I look at the video I see someone who never misses a shot and is a 100 percent free-throw shooter. I'd say that should mitigate any concerns about her having a missing limb.
Seriously though, the play in that video that sums up what makes Diamond so special is when she finished the lay-up while contorted like crazy after being fouled. At no time during that play was Diamond off-balance in her upper body. She took the foul and somehow managed to turn the unexpected change of momentum into a very fluid, under-control finish. Watch it slowly and pay close attention to her head, eyes, and the rest of her upper body. She makes plays like that look routine.
There are girls who are faster. There are girls who are better shooters. There are girls who can jump higher. There might even be a girl who has more of each of those qualities. But I've never seen a girl like that who has the balance and control that Diamond has while she is on -- or above -- the court.
