Admittedly the press said his time this year was faster than Bolt's (good old general popular BBC reporting), but they declined to say Bolt's was into a significant headwind. More was made of it being the second fastest UK time to Linford Christie.
Dasaolu basically ran a one race final for the time I think, which was costly as the final then got a +1.9m/s headwind and theoretically he could've just broken straight into the 9.8s! Really he should have had sub-10 earlier on this year, as he did do the 10.05 into a -1.3 head wind. So, no doubt Bolt is faster but now he looks like a genuine semi-final/final shout. Similar with Vicaut who just impressed with a 9.95 in the French final.
Much has been made of the picking rules here in the UK, but despite tightening up some of the standards by quite a lot, cutting down the amount of auto picks, it still seems to be mainly down to who the selectors want to pick. In the USAs, it is all on the finals, which has had benefits, but also failures. I'm thinking here of Tyson Gay 2008. I guess it makes sense to have such a system, given the high level of competition in the US. The complexity of the distance selection was entertaining, if bloody hard to follow, and it seems we have something similar here too (excepting the mandatory trials part).
Bolt false starting again - I just can't see happening, unless he is still out of shape and needs a fast start (more likely with Gay back in such form). Dasaolu beating Bolt would be very lolworthy.
