WOW! I agree, Sanya’s 10.89 converts to about 11 flat, which is about were her 100m speed was when she was running 48s.
Allyson has fecklessly strong and balanced calf and hamstring strength, but her gluteus don't match up. In spite of her slight build, she is amazing in the weight room. Her top-end is as fast as the best 100m sprinters, but she doesn’t and never has had great explosive acceleration and in spite of working on her start, she still reacts slowly to the gun. Her 7.1 60m indoors is about the best start she has ever had, even though it was only average by world-class standards. Her drive phase problems is a matter of her physiology, but her reaction is a mental thing. Allyson is an 11 flat 100m sprinter on a good day and is not a consistent top 4 among U.S. 100m sprinters, but she is a monster on the 400m relay. The running start helps her and she hands off at top speed, when the other girls are slowing down. Which is why even if she doesn't not run a credible 100m this year, she will still be placed on the 400m relay and no one will complain about it.
Allyson has always viewed herself as 100/200 sprinters and was sort of pushed into the 400, but she has never liked the 400 and in my mind, is still not 100% committed to it. She still runs the 400m expecting to walk people down and she can't do that because the top 400m sprinters may not have her 100m speed, but are just as strong over the last 50 meters. If Allyson ever gets it right in the 400m, I think she can challenge the U.S. record. With that said, with Sanya returning to form in the 400, VCB does not appear to be slowing down, Jeter will have full season to focus on the 200m and the possibility of Sanya jumping into the 200, the 200/400 double looks very daunting. I think Allyson is capable of winning either the 200 or the 400 if she completely focuses on one, trying to do both, she is probably looking at a silver and bronze at best. If Allyson never ran another race, she will be regarded as one of the greatest sprinters of all time, but she needs an Olympic gold medal to complete her resume and I’m hoping she drops the 200m or the 400m.
