My thinking is that Rudisha's problem vis-a-vis this Amos kid is largely psychological -- Rudisha is losing that dominant, mental edge and, perhaps, developing a fear and block every time he lines up against the Botswanan.
On a different note, whatever happened to the best ever Kenyan middle and long distance athlete -- better than Kip Keino, or Henry Rono or Paul Tergat or Moses Kiptanui.
Of course I am talking about Daniel Komen.
