Mo is the greatest of all time in slow track finals and happens to have the endurance to run a 59 half. He only ran 3:28 those 2 times cause Kiprop went HAM in those races and ran 3:27 in 2013 and 3:26 this year. I'd say Mo is kinda scared to go for a world record outdoors cause of the possibility of blowing up...when was the last time he ever went straight record attempt? He never runs races where he gaps the field early. Bekele did that COUNTLESS times...and my favorite was when he ran his 7:25 3k PR off of a slow first 800. Farah's too caught up in his image to try and run a world record...GOAT? Nah, but one of the greatest of all time? Absolutely.
