Next year's 100 at Beijing is going to be sick. I'm not surprised at all about Powell, he's obviously damn good. This does make his performance at worlds pretty surprising, but whatever, I guess he's just a choker. Better work on that before next year, Asafa!
It is amazing how dominant Greene was. He has to be the best 100 guy of all time. Completely dominant in both times and championships, and his times still hold up extremely well (obviously it hasn't been that long, but still).
It's interesting how the times in the sprints kind of levelled off in the 80's. Think about it, Carl Lewis was pretty much just as fast as Mo Greene. But then, the distance didn't start to level off until like the mid 90's, and you could argue, especially in the 10k, that it hasn't stopped yet.
