If he were given the same set up, I think he would hit it. He is the only man to run sub 2:04 4 times, so he has the endurance and speed. And i think he runs more relaxed than Kipchoge and gets better as the race goes on.
Possibly throw Kimetto in there as well since he is a 2:02 guy, but he hasn't looked good since then,.
Bekele just isn't consistent or dependable, which is why Nike probably didn't to him. Other Kipchoge and Bek, Nike doesn't have anymore really fast marathon guys. ghirmay and Feyisa showed in London that they don't have that speed.
I think Adidas has a bigger stable of fast marathoners who they could throw out there.
