The argument isn't whether Mo GOAT now but whether he could be by 2016 or 2017.
And by the amount of people chiming in on this thread, I think it is an interesting topic. I've quite enjoyed it.
From the title to the thread, it sure SEEMS like it is whether Mo is the GOAT now.
Mo just split 3:33 en route to his best ever 2 mile time. Bernie was 4 seconds behind that at age 40. To be the GOAT, you have to be more than 4 seconds ahead of a 40 year old man; even Bernie. If a 40 year old man is within 10 seconds of you over 3k, you're not the Goat.
Assuming the big 3 (Geb, KB and Mo, along with others like Tergat, Komen, etc) are clean .....
I don't think it's unreasonable to compare times over distances for these guys. I wouldn't compare Jim Ryun's time with El G or Asbel, but KB and Mo? Of course those are comparable. And Mo isn't in the ballpark.
His medals are great achievements, and I'm not at all belittling those. But he hasn't run anywhere near as fast as LOTS of other guys. He's not even as fast as Galen over 10 000m, and marginally faster than Galen's half Marathon.
