Bekele's first 5k was run much, much slower than Farah's first 5k, in case the maths eludes you:
26:49-12:57 = 13:52
We have NO IDEA however fast Farah 'coulda, woulda, shoulda' run his second 5k given such a pedestrian start.
As I said, you cannot compare two tactical races especially in events as long and varied as the 10k. The pacing throughout both races was VASTLY different.
I'm not saying Bekele or Farah are better than the other, I'm saying you cannot look at one race over the other and say X runner would have won Y race.
Farahs last 120m was rapid, he found an extra gear no other 10k runner has ever shown. He only did enough to win on the last lap. How can you say with certainty that with Bekele on his shoulder he wouldn't push harder in the last 800m. Farah didn't look tired to me. Or that bekele wouldn't be tired from leading with Farah sitting on him, and Farah the 3:28 man might breeze past in the last 60m as El G did in 2004? You just DON'T KNOW.
Therefore it's conjecture with the aim of only trying to belittle Farah's achievements and it's a poor show by you.
