First off, Aborigine's have no relation to Africans as far as everything that I have read. So Patrick Johnson is the first man of non african ancestry to do it. The media and fans will just always lable him as part black because some of the aborigine's looks are similar to blacks. I have seen whites that also have big lips, noses, long legs, short torso but where white as snow.
As for Pickering, I am standing by my prediction. He will
go sub 10 this year barring another serious injury. They will continue to work on his form. He has the power, speed and stamina down pat. I still think running a few 200 meters races would do him some good. He doesn't have to win but it will give him a better base and a little more speed endurance.
Running sub 10 requires many aspects from mental to physical. I think that one of the greatest things that alot of white sprinters need to work on is to relax more. Not only the mental edge but learning to let your speed carry you through the finish line without tieing up. You can only run all out for 60-70 meters. Then it is the guys who relax the best who win the races.
Shirvo never had good form. He was choppy and had trouble staying in his lanes. I loved the guy but he needed some serious help with his form. With his speed and power, he should have went sub 10 multiple times and at least made several major finals. It's very sad the Khmel couldn't coach him better. Just my opinion.
