Blake's sprint wasn't superior in any way.
Although I have been Blake's biggest advocate on this board, and pointed out early on in his development that HE was the one to watch for, Bolt cannot be underestimated.
Both guys are great. Right now I would say that Blake would have a slight edge in a head-to-head, because he is so consistent...but for no other reason than that. Bolt could easily lose to him, or could just as easily blow him away right now, there is just no telling.
Look at Bolt's race...his drive phase was actually pretty good, his transition was acceptable, and by his standards, his finish was mediocre.
IMHO Bolt is going about it EXACTLY the right way. The start and drive are the hardest to get right, whereas the finish can come with training volume.
Blake's start is now OK, his drive phase is OK, but his transition looks great, and his finish is solid.
Bottom line, I still don't think that Blake has the same envelope as does Bolt in the 100m.
Right now there is no edge to either, they are both all over the place form-wise and fitness-wise.
If, IF Bolt hits his top gear using his Daegu relay anchor form, he will set a new 100m WR this year.
However, I believe that Bolt has a much greater chance of injury than does Blake. Blake's form is very smooth, with very good turnover and feel for the track. Bolt's is more bombastic, with more attack, and Bolt is much longer and thinner than Blake.
Blake is taking over where Gay left off--their running styles are nearly identical as far as I can tell.
Right now there is no reason to suspect that he will go any faster than Gay did at his peak, although he will achieve that level sooner.
Unless, of course, you believe Gay to be clean and Blake to be doping (as I do).
But, however low Blake can dope to, I still think that Bolt could dope .10 faster.
Blake's consistency is amazing now--in terms of performance, he is every bit Maurice Greene's equal. He will go faster than 9.79, however.
