Evan is too long to be able to turnover on the last lap the way Kipruto can. He is also much more of a rhythm runner like Rupp and needs to grind people down before the last lap. Kipruto has always been able to out kick him.
I think Evan should try to move up in distance after 2020. At 29, his kick is not going to get much better. He will easily make the Olympics, but there will always be an E. African who can close better. He is an incredibly smooth and efficient runner. He could be surprisingly good at longer distances.
