Blake is no more 'on par' with Bolt than Tyson is, certainly over 100m. They both have a recorded best of 9.69. And Tyson also has a 9.71, so if anyone has a claim to being closer to par with Bolt there, it's Tyson. And Bolt has run well under that TWICE. Neither of those athletes are on par with Bolt.
Blake's 200m time is 0.07 seconds slower than Bolt. Not a huge margin, but not 'on par' either.
I think you're doing exactly what you're accusing Ventolin of doing; reaching for a 'What if' ... Blake hasn't run any faster than Tyson did. Blake ran quite a bit slower than Bolt did this year, was smoked by Bolt in the OG, and hasn't got near the WR. To surmise that he may be able to one day is no different to guessing what a healthy Tyson might run, or Asafa if he was taller, or Lemaitre if he was blacker.
